Assembling a homemade compass<\/h3>\n
Cut off a small piece of floating material. Most importantly, it should be sized to ensure the buoyancy of the needle attached to it, and at the same time that it should be sized so that the surface tension of the water and the drag forces are negligible – this is necessary to ensure accurate readings.<\/p>\n
The needle will play the role of an arrow. First you need to make sure that one end of the needle is magnetized and the other is not. If you have magnets at hand (they are present in the speakers of the player, receiver, in electric motors, etc.), then you can magnetize the needle-arrow using them. If there are no magnets, then you can simply hold one end of the needle over the flame for 25-35 seconds, after which this tip will be demagnetized (if you were interested in physics at school, then you understand why this is happening). So the arrow is ready. Its magnetized end will be a pointer to Serer, and its non-magnetized end will be a pointer to the South.<\/p>\n
We attach the needle-arrow to the float. It is most convenient to carefully pierce the float with a needle along the axis of symmetry. Such fastening is simple and reliable at the same time. It remains just to place the float with an arrow in a container with water in such a way that the walls of the container do not interfere with the rotation of the arrow. The compass is ready, it remains to calibrate it.<\/p>\n
If you know which tip of your needle was magnetized and which is not, then you can immediately judge where the north is by the position of the magnetized tip. If you do not know, then the following facts will help you determine where the North and South are: the place where the sun rises and where it sets (Rise-East, Sunset-West) or the position of the pole star. Using these signs, you can easily calibrate your homemade compass.<\/p>\n

As you can see, making a compass yourself is not that difficult. On the one hand, we looked at interesting solutions, but if you dig deeper, it becomes obvious that we have replenished our knowledge box with extremely useful information! Happy travels, friends.
\n<iframe src = ” https:\/\/www.youtube.com\/embed\/qxUWFVloCok<\/a> “><\/p>\nWhy do we need a compass in the game?<\/h2>\n
As you know, dear friends, in the human world, in unfamiliar places without navigation systems, it is easy to go astray. And therefore, everyone who sets out on a long journey must take a compass with them on the road.<\/p>\n
With us, in minecraft, sometimes you have to get quite far from home. In search of resources needed to create other useful things in minecraft, various villages and mines, and in general in travels out of pure curiosity. Therefore, it is also very important for us to have this important navigation system. In addition, it will also be needed later, to create another important item in minecraft, namely a map, which is also a useful thing in wandering around minecraft.<\/p>\n
![\"How](\"https:\/\/inform.com.de\/wp-content\/uploads\/2021\/04\/post-183054-607bdead0abc3.jpg\")
<\/a><\/p>\n3 facts about the compass<\/h3>\n
Many of us are probably familiar with the situation when, having climbed quite far from the home and not knowing to leave along the way, even landmarks in the form of blocks, for example, land, we suddenly find that we are literally lost. And then, for a long time, we wander in search of our home. And in order to avoid this unpleasant situation, and not to get lost in the endless expanses of our cube world of minecraft, we need to acquire a reliable navigation system:<\/p>\n
- \n
- He will always show us the right direction, but of course, not to the north, but to the point of our spawn. This is where we first appear in the game. By the way, friends, I would advise, having appeared for the first time in the game, to build your dwellings exactly in the place where they appeared, or close to this place<\/li>\n
- you don't need to hold it in your hand, it always works in minecraft, wherever it is:<\/li>\n
- Unlike single player, where he points to the spawn point, in multiplayer, he points to our bed.<\/li>\n<\/ol>\n
How to craft a compass in Minecraft<\/h2>\n
In order to make a compass in a minecraft game, we need: iron ingots and red dust. Let's place them on the workbench in a certain way:<\/p>\n
![\"How](\"https:\/\/inform.com.de\/wp-content\/uploads\/2021\/04\/post-183054-607bdeadb8a27.jpg\")
<\/a><\/p>\nWhat items are needed for crafting?<\/h3>\n
To make an important navigation system for us, we will have to, my friends, work a little and get the necessary items. You may have to go deep underground, in mines, to find the necessary ore and coal. We also need an oven. I hope you already have it, if not, be sure to read our how to make a stove in minecraft. And we also need red dust. I will tell you how to get it a little later.<\/p>\n
How do I get the iron ingots I need for crafting?<\/h3>\n
In order to make the required ingots that we need when receiving our navigation device, it is necessary: \u200b\u200bto make a stone pickaxe, to extract iron ore in mines and melt it in a furnace. To do this, we place coal in the lower square, and the ore in the upper one and after smelting we get the ingots we need:<\/p>\n

<\/a><\/p>\nHow to find red dust?<\/h3>\n
So now we need to get red dust. We will not do it, but we will extract it in mines underground. For this we need a pickaxe, which must be at least iron. When the ore is destroyed, about five units of dust fall out of it. This is a very popular thing in minecraft, we will need it to create many other items.<\/p>\n

How to use a compass in Minecraft<\/h3>\n
\n
On dry land with a staff, on the sea – with a compass (proverb).<\/p>\n<\/blockquote>\n
The main thing is to craft a compass or get it in some other way. The rest is a matter of technology, but it depends on the version and mode of the game. If the compass does not point to the bed, then you are probably in Hell or Ender, or you are playing in Minecraft's single player mode. Since in this case the arrow is directed to the point of first appearance. And in multiplayer mode, the compass will indicate the direction of your spawn. This is the secret and the answer to the question: “where does the compass show in Minecraft?”.<\/p>\n
Changes to the use of this item appeared in Minecraft version 1.9. When the compass is thrown or recorded in the game statistics, it does not show the direction to the spawn point and the arrow only looks north.<\/p>\n
How to make a homemade compass<\/h2>\n
Speaking about the construction of a home-made compass, one could just give the algorithm for its creation and end there. However, it seems to me, despite the simplicity of this approach, it limits the reader's diversity and forces him to look at the question in a narrowly focused way, excluding the possibility of improvisation in a situation when it becomes necessary to make a compass with his own hands.<\/p>\n
In this regard, I propose to consider not a specific algorithm for creating a compass, but its stages, which could be discussed in more detail, having understood their essence and subtleties, and thereby fully revealing their potential.<\/p>\n
So, the whole process of creating a compass is divided into several stages:<\/p>\n
- \n
- At the very beginning, a search is made for an object that will act as an arrow.<\/li>\n
- At the second stage, this object is magnetized.<\/li>\n
- The homemade compass needle is then provided with the least friction conditions so that it can rotate along the lines of force of the Earth's magnetic field and indicate the direction to magnetic north and south.<\/li>\n<\/ol>\n
If necessary, for the correct operation of the arrow, wind protection is used, because you will most likely have to work with such a compass not at home, but in nature, where windy weather is the norm.<\/p>\n
By the way, one of the first compasses that appeared in Europe was a magnetized needle floating on a cork in a vessel with water.<\/p>\n
Next, step by step, we will consider the entire process of making the simplest navigation tool.<\/p>\n
Compass needle material<\/h3>\n
To create a primitive means of navigation, which is a magnetic compass, you need to have an object made of ferromagnet – a material that can have magnetic properties in the absence of an external magnetic field. Such a material can be easily identified by holding a permanent magnet to it – ferromagnets will be easily magnetized.<\/p>\n
In fact, diamagnets can also interact with a magnetic field, but for this you need to create a very strong magnetic field. For example, an experiment is well known where a frog levitates in a magnetic field. It is shown in the video:<\/p>\n
The well-known “household” ferromagnets mainly include articles made of iron and its alloys. Items such as a nail, a steel knife and scissors, a safety pin, a sewing needle, and a fish hook are all ferromagnetic products and are all suitable for a homemade arrow.<\/p>\n
The most convenient of them will be those that have less weight and size. This will become quite apparent when we look at the next steps.<\/p>\n
However, in the absence of a miniature “arrow”, it is quite possible to use more cumbersome options.<\/p>\n
Considering the subsequent steps, for example, let's imagine that a sewing needle was chosen as the magnetic needle – the most popular version of the arrow for a homemade compass.<\/p>\n
Magnetizing an improvised arrow<\/h3>\n
In order for the needle – the future needle of the compass – to turn in the earth's magnetic field, it must be magnetized.<\/p>\n
Often, ferromagnetic objects used as arrows may already be magnetized.<\/p>\n
It is with this, it seems to me, that most of the misconceptions are connected, where people believe that they were able to magnetize an object, using in fact completely unsuitable methods for this. For example, they try to magnetize the needle by rubbing it against the hair. In other words, in this case there is an error in determining the cause-and-effect relationships.<\/p>\n
In the field, it is quite simple to check whether an object is magnetized or not: you need to make a compass out of it and see if the arrow turns. How exactly this is done, we will describe below.<\/p>\n
In this case, after a complete stop of the “arrow”, turn it in one direction, then in the other. If such an arrow constantly returns to the same position, then it is magnetized and it is not necessary to additionally magnetize it. By the way, in the same way, the serviceability of a compass made in production is checked.<\/p>\n
If the arrow was not magnetized, then it can be magnetized in two ways.<\/p>\n
Method number 1 – using a magnet. This is the easiest and fastest way.<\/p>\n
To do this, just put the arrow next to the magnet. In wild conditions, it is often suggested to remove the magnet from the speakers of the headphones or phone. However, as for me, this is irrational: the phone may still come in handy. Everything is much simpler: just put the arrow on the phone or walkie-talkie itself to magnetize it, but it's even easier to put it on a steel knife, which, as a rule, has magnetic properties.<\/p>\n
It is not necessary to hold the arrow near such a magnet for a long time: usually a few seconds are enough.<\/p>\n
The determination of the sides of an improvised arrow occurs empirically using the stars or the Sun.<\/strong> That is, the sides of the world are determined by the luminaries, and then it is determined which part of the arrow points to where. And we talked about how to determine the cardinal directions by the Sun and the stars here (Orientation by the Sun) and here (Orientation by the Pole Star).<\/p>\n
Method number 2 – using a coil and current. This method is more complicated and requires an insulated wire and a current source.<\/p>\n
In this method, an insulated wire is wound around the needle in the form of a coil in one layer. If the wire turns out to be bare, then the needle can be covered with dry toilet paper or a piece of polyethylene to insulate it from contact with the wire, and make the turns so that they do not touch each other.<\/p>\n
An electric current is passed through the coil, as a result of which a magnetic field arises inside the coil, and the needle becomes the core of this electromagnet.<\/p>\n
Where can I get electricity for this method? It's simple: most often, a flashlight battery or a phone battery acts as a power source in the wild, although there are other sources. The main thing is that the current is constant, not alternating, that is, an outlet without additional circuits that equalize the electric current will not work for this.<\/p>\n
To determine which side of the needle points north, you can use the method proposed in the first method. However, there is another option.<\/p>\n
To do this, you need to remember the physics and the gimbal rule. With regard to this case, focusing on this rule, we can say that the gimbal will move in the direction where the improvised arrow will have the northern end. It is this end of the arrow that will point towards the north magnetic pole of the earth.<\/p>\n
Now that the main part of the work has been done, the only thing left is to enable the arrow to rotate freely. To do this, you need to properly secure it.<\/p>\n
How to attach an arrow to a compass<\/h3>\n
In fact, unlike factory models, it is not at all necessary to attach the arrow in any special way. Usually, to reduce friction, the needle is either placed in water or suspended from a thin thread or fishing line. But there are some nuances here, which we will talk about.<\/p>\n
For the variant with water, you can use a puddle or other natural body of water. But in the second case, there is a danger of losing the needle due to its drowning.<\/p>\n
Containers, such as a plastic plate or aluminum pot, are also good options, in which you can pour water and lower the needle onto it. In this case, it is important to ensure that the cookware does not have ferromagnetic parts. For example, a bowler hat may have steel handles that cause changes in the readings of a homemade compass.<\/p>\n
The photo below shows a disposable plastic plate filled with water, in which a needle floats, fixed on a piece of waterproof cloth – this is the compass of their improvised materials:<\/p>\n
![\"How](\"https:\/\/inform.com.de\/wp-content\/uploads\/2021\/04\/post-183054-607bdeaf341e3.jpg\")
<\/a><\/p>\nA good option for a “water” compass is polyethylene placed in a depression in the ground or sand and filled with water.<\/p>\n
It is also worth making sure that the surface of the water remains clean, because a film formed by any substances or microscopic living organisms can also greatly affect the operation of a homemade compass, preventing the arrow from rotating.<\/p>\n
If the needle is very small and accordingly light, then it can be slowly put into the water – and it will remain afloat due to the forces of surface tension. For this, it is important that the surface of the needle remains dry before it enters the water.<\/p>\n
However, it will not work to keep the gypsy needle on the water in this way due to its large mass. Therefore, such a needle can be placed on a leaf of a tree or bush, or it can be inserted into a hollow dry stem of a plant that has sufficient buoyancy to keep the needle on the surface of the water.<\/p>\n
Also, a piece of foam, a plastic bottle cap and many other lightweight materials that do not cause magnetic deviations, which we talked about in detail here (Magnetic Compass), can also serve as a floating device for the needle.<\/p>\n
It is important that during measurements the needle on the “boat” does not touch the walls of the vessel or the “banks” of the puddle, since in this case friction will not allow the needle to rotate freely.<\/p>\n
Thus, thanks to water, it is possible to achieve the least resistance, and the needle itself turns and points to north and south, even being weakly magnetized.<\/p>\n
If you plan to hang the needle on a thread, then you can make a running simple knot on the thread, which, under the weight of the needle, will additionally tighten, preventing it from slipping too much. In this case, the needle should be suspended approximately in the middle with a slight displacement towards the ear, that is, the part is heavier. The exact place where the thread is attached to the needle is chosen empirically.<\/p>\n
By the way, instead of a thread or fishing line, a long human hair is quite suitable. I was able to achieve good results using this particular material. The video shows how to do this:<\/p>\n
In order for the needle to slip out of the loop less, I wrapped it with two or three layers of toilet paper. In addition, this option, due to the windage, allows the arrow to “calm down” faster, which significantly speeds up the work with the compass.<\/p>\n
It is very important for this option to use the thinnest and longest thread or fishing line, since only in this case it will be possible to sufficiently minimize the effect of material twisting, which can cause a large error in measurements.<\/p>\n
Of these two, the option with water can rightfully be called the best, since it is he who gives the minimum errors and allows the improvised arrow to quickly stabilize.<\/p>\n
So we examined the device of the simplest magnetic compass. However, in this version, the compass will be able to work mainly only at home: in nature, the design of a homemade compass will have to be supplemented with a windbreak. This is especially important for a compass using a pendant arrow attachment scheme.<\/p>\n
Wind protection<\/h3>\n
Most often, a plastic transparent bottle cut in the middle is offered as a wind barrier. This option, as for me, is not very convenient for either a “water” or a “string” compass. In the first case, it will be difficult to keep the needle in the center of the volume, and it may come into contact with the walls, which, as we remember, leads to measurement errors. In the second case, due to a too short thread, forces associated with the thread's resistance to twisting will act on the needle, which will also negatively affect the readings.<\/p>\n
As a windbreak, I personally would suggest natural shelters, combined with additional protection from the wind by my own body.<\/strong> Also, an aluminum pot does an excellent job with this, representing both a container for water and protection from the wind. However, this option is only effective for a “water” compass. For a needle on a thread, you can use karimat by twisting it into a tube and placing it vertically: this way you get a good protection from the wind with a sufficiently long thread to which the needle is suspended.<\/p>\n
If karimat, polyethylene or other materials for creating an artificial windbreak are not available, the area does not have natural shelters, and the weather leaves much to be desired, then you need to use what you have, or wait until the weather calms down or clears up to move on to orientation methods by heavenly bodies.<\/p>\n
And now, as promised, let's look at the most common misconceptions associated with this topic.<\/p>\n
Misconceptions and their denials<\/h3>\n
As the source of the most popular misconceptions, I chose the well-known book on survival “The book that will save your life” by the no less famous Soviet extreme tourist Andrei Aleksandrovich Ilyin. Who knows, perhaps it was she who caused the myths that spread and became entrenched in the minds of people.<\/p>\n
So, consider the “magnificent seven” of the most common myths associated with the construction of a homemade compass.<\/p>\n
Misconception No. 1. When building a homemade magnetic compass, you can use a needle as the axis for the arrow, which must be stuck into the base of the compass with the eye down.<\/strong><\/p>\n
Rebuttal: the compass should not contain ferromagnetic elements, except for the needle itself. Otherwise, there are distortions in the compass readings associated with magnetic deviations.<\/p>\n
Misconception No. 2. In order to magnetize the needle located in the coil through which the electric current flows, you need to spend at least 10 minutes.<\/strong><\/p>\n
Rebuttal: experience has shown that for magnetizing the needle in this way, no more than 5-10 seconds is sufficient. At the same time, in order to re-magnetize the needle and change its poles to opposite ones, no more than 10 seconds is also enough. Spending additional time is not only useless, but also harmful, because in addition to temporary losses, the power source is discharged, which could be suitable for other purposes, for example, for starting a fire.<\/p>\n
Misconception No. 3. The northern end of the needle magnetized in the electric coil will be the end from which the negative terminal of the battery was connected.<\/strong><\/p>\n
Rebuttal: the north end of the needle is determined by the gimbal rule, also known as the right hand rule. And according to this rule, the northern end will not always be the one on the side of which the negative terminal was connected: here the direction of the winding turns will also play a role.<\/p>\n
Misconception # 4: For the needle to lie on the water, held by the forces of surface tension, it must be rubbed against the hair or between the fingers.<\/strong><\/p>\n
Rebuttal: even a needle completely defatted with ethanol will stick to the surface of the water. If its mass is too large for this, as is the case with the gypsy needle, then no amount of friction on the hair and skin will help the case.<\/p>\n
Misconception # 5. You cannot use metal containers for a homemade compass.<\/strong><\/p>\n
Rebuttal: the point is not whether the dishes are metal, but whether the material from which the dishes are made is ferromagnetic. Thus, you can also use metal dishes. For example, the accuracy of measurements of a home-made compass will not be affected by aluminum, magnesium or copper, which are inherently not ferromagnets, but para- and diamagnets.<\/p>\n
Misconception # 6. Do not use salt water.<\/strong><\/p>\n
Rebuttal: the presence of salt in the water does not have a noticeable effect on the readings of a homemade compass. This is also easy to see for yourself by conducting your own experiment with salt water and a magnetized needle.<\/p>\n
It is also worth telling about another very common misconception, which is not directly related to the mentioned book, but is firmly rooted in the heads of many tourists and survivalists.<\/p>\n
Misconception No. 7. You can magnetize the needle by rubbing it on your hair or on a woolen product.<\/strong><\/p>\n
Refutation: it is impossible to magnetize the metal needle in this way, which can be easily seen in the experiment.<\/p>\n
I believe that the author's fame and the innate tendency of people to trust authorities are the reason why these misconceptions have gained such widespread popularity.<\/p>\n
Compass on a thread and a needle<\/h4>\n
In fact, making a compass for their needles and threads is very simple and most importantly effective! To begin with, we take an ordinary needle, it can be found in everyone somewhere at home. Then, as follows, three it with a magnet so that it becomes magnetized. The next step is to take any thread, if you are on a hike, and the reel is not with you, you can tear it off any clothing. Next, we lift the thread into a needle and tie it to a knot. Carefully, it is advisable not to take it too tightly in your hands, it can transfer the charge to you and thereby demagnetize.<\/p>\n
Lay it flat and watch. One end of the needle will point north and the other end will point south. The east and west sides of the world will be located on the right and left sides. Note which end showed the north, this can be done with green paint, iodine, which travelers will always find. That's all. You can safely determine the cardinal points by it, like a standard compass.<\/p>\n
How to make a compass from a needle and water<\/h4>\n
Another easy way to make a compass is with a needle and water. This is a very handy method for making a compass at home. So, to make a compass using this method, you need to take a needle. Magnetize it properly, this can be done with a magnet. Rub the needle against it, but not with the whole part, but only with one end. The other end must not be charged. To discharge it, you can hold it over a fire, this will neutralize the charge. If you do not have a special magnet, you can use any, even the smallest one, such is on the refrigerator. Or use silk, it charges objects like no other.<\/p>\n
The next step is to mark with color which side is magnetized so as not to confuse the sides. You can mark it with any paint or brilliant green, iodine or some other impurities. Next, the most interesting thing is, pour water into a bowl, set the needle on a stable surface that will stay on the water (pinoplast, cork from wine, plastics, and any other objects that stick to the surface of the water). Next, you need to watch. The arrow will turn in the direction directed to the north, behind it will be the south, and on the right and left sides there will be a direction to the east and west .. Here is such a way! Very lightweight and effective in any terrain.<\/p>\n
Paperclip compass<\/h4>\n
So, to make a compass out of a paper clip, you need to properly charge it. This can be done with the help of a magnet known to all, or you can recall the physics of the seventh grade and use silk. Rub it to keep it charged. Next, you need to carefully place the paperclip on a cardboard or paper surface and lower it into the water. Make sure that nothing interferes with the movement of the paper clip. Eliminate all kinds of drafts, gusts of wind. It is also worth using a small piece of paper to avoid hitting the bowl of water. That's all, the compass is ready. If you did everything correctly, then he will show you the way to the north. Have a good trip!<\/p>\n
How to make a cut and a hole in a compass<\/h4>\n
How to make a compass in 3d? To do this, you need to draw the correct drawing. There should be several such drawings from different sides. Top view, left side and interior. This is all done using different programs that are made specifically for these purposes. They are easy enough to use. On the drawing, you need to indicate the main markings, they are indicated by a thick line. Thanks to this method, you can make different types.<\/p>\n
To design a homemade compass you will need:<\/h2>\n
![\"How](\"https:\/\/inform.com.de\/wp-content\/uploads\/2021\/12\/44c1b0ec404c446cd7db24c5c7eb8631-1.png\")
<\/a><\/p>\n\u2022 Separate magnet with north and south poles<\/p>\n
\u2022 A small bowl of water<\/p>\n
Homemade compass is done as follows<\/h3>\n
1 Pass the north pole of the magnet along the needle, from ear to tip, at least ten, twenty times. This will magnetize the needle.<\/p>\n
2 Cut a small piece from the end of the cork. About ten, twelve millimeters will be enough.<\/p>\n
3 Pass the needle through the cork from the side of one circle to the other.<\/p>\n
4 Fill a bowl with water (half is enough). Dip the cork and needle into the water.<\/p>\n
5 Place your homemade compass on a flat surface and watch what happens. The end of the needle will point north.<\/p>\n
How a homemade compass works<\/h3>\n
![\"How](\"https:\/\/inform.com.de\/wp-content\/uploads\/2021\/12\/e4d3eafbe9c5af9a44592a82789d8ff9-1.png\")
<\/a><\/p>\nThe magnet has the ability to attract iron, steel, and other magnets. A magnet has south and north poles, and the north pole of one magnet and the south pole of another magnet are attracted to each other. The core of the earth is rich in iron, so the earth is a magnet, with north and south poles. The Earth's magnetic field is not strong enough to completely pull all other magnets toward the south or north poles, but strong enough to turn them around.<\/p>\n
Since the magnetized needle, stuck into the cork, floats on the water, it can freely rotate and unfold in accordance with the magnetic poles of the Earth. This is the easiest homemade compass that can tell you where is north and where is south. If we put our homemade compass on a piece of cardboard, then after the needle points to the north, we can mark all cardinal directions on this cardboard. And then you will constantly know which side is north, south, west and east.<\/p>\n
The South Pole is the only place on Earth where any direction points north.<\/p>\n
Who has their own internal compass?<\/h3>\n
Honeybees navigate space using the sun as a magnet. And bats contain a magnetic substance called magnetite in their bodies, which they use as an “internal compass” to help them navigate through space.<\/p>\n
Assembling the structure<\/h3>\n
We make a compass needle and magnetize it, as described in the previous instructions. You can use a needle or a safety razor blade to make an arrow. You can also make an arrow from a half of a razor blade.<\/p>\n
We tie a thread or fishing line to an impromptu arrow in its center of gravity. We place the arrow inside the transparent vessel so that it is suspended. The vessel will protect our structure from the wind.<\/p>\n
We calibrate the resulting compass according to the method described in the last paragraph of the previous instruction and get the device ready to use.<\/p>\n
As you can see, making a compass yourself is not that difficult. On the one hand, we looked at interesting solutions, but if you dig deeper, it becomes obvious that we have replenished our knowledge box with extremely useful information! Happy travels, friends.<\/p>\n
Compass made of blade and battery<\/h2>\n
If you are in the field and do not have a magnet or silk cloth, then a compass can be built from a blade, battery and wire. If you have a coil of insulated wire, wind it around the blade, making 5-7 turns. If there is no insulation, then first wrap the blade with one layer of paper, and then wind the wire. Connect the wires to the battery by connecting one of them to the plus and the other to the minus. The higher the battery voltage, the better, but not less 2.<\/p>\n
Leave this construction on for an hour and then free the blade by disconnecting the wires. Put it on a piece of paper and lower it in the water. The part of the blade on which the last turn of the wire leading to the minus was located will turn to the north, and the side connected to the plus to the south. You can replace the blade with a needle or a paper clip. The main thing is that it should be a light metal object, by the shape of which you can understand where it is pointing.<\/p>\n
How to make a compass<\/strong> when the standard compass<\/strong> was lost or out of order in the field ?<\/p>\n
This requires certain materials at hand, an understanding of the principle of operation of the device and a little ingenuity.<\/p>\n
The principle of the compass is based on the phenomenon that any magnet tends to align itself along the lines of force of the Earth's magnetic field. The lines of force are oriented north-south. Consequently, the magnet will be oriented in the same direction. The compass needle is a small magnet.<\/p>\n
In order to make a compass,<\/strong> we need a magnetic needle and the ability to position it so that as little extraneous forces as possible prevent it from turning along the lines of force of the Earth's magnetic field.<\/p>\n
Best of all, a linear magnet would act as a compass needle. And from the materials at hand, steel is magnetized best<\/p>\n
Therefore, the best way to make a compass is to use a sewing needle as a magnetic needle. You can use a pin, a piece of steel wire, strings, for example, or other steel items. Any small steel strip can also work – a regular razor blade, for example, or half of it.<\/p>\n
How to make a compass using a needle.<\/h3>\n
To make a compass using a needle as an arrow, it must be magnetized. To do this, rub it against a magnet or stick it to it for a few minutes.<\/p>\n
You can use a magnet from a radio speaker, audio player, or from headphones to them.<\/p>\n
And how to make a compass when there is no magnet?<\/p>\n
For magnetization, in this case, you can make an electromagnet using a battery and a piece of thin wire.<\/p>\n
Having wrapped the needle with some insulating material, paper or cloth, for example, we wind as many turns of wire on it as possible, creating a winding of the electromagnet.<\/p>\n
We connect the ends of the wire to the battery terminals.<\/p>\n
Moreover, it is important to know what the end of the needle to which the end of the wire connected to the negative terminal of the battery approaches will point to the north.<\/p>\n
And if we have neither a magnet nor a battery?<\/p>\n
Then you can magnetize the needle by rubbing it vigorously on silk or woolen fabric.<\/p>\n
Or your own hair. (More about this original method in the video at the end of the article).<\/p>\n
The needle is magnetized, also if one end of it is heated red hot over a fire, cooled in air, and the other end is rubbed between the fingers.<\/p>\n
To make a compass, you need to ensure that the needle floats on the surface of the water – in a puddle or in a container with water. The container should be made of non-magnetic material, and there should be no objects made of iron or power lines nearby.<\/p>\n
Sometimes the needle floats on the surface due to surface tension forces. But it is easier to make it float by smearing it with some kind of fat.<\/p>\n
You can also put it on some floating object – a piece of paper, a piece of wood, a piece of bark, cork or foam. Or shove it in a straw.<\/p>\n
If the conditions are met correctly, the needle will be positioned in the north-south direction.<\/p>\n
If we do not know which end of it points to north, we can navigate by<\/p>\n
Let's think about how to make a compass when there is no water in which an impromptu arrow would float.<\/p>\n
In this case, you can make a compass by hanging a needle or, for example, a razor blade on a thread, tying it at the center of gravity. The thread should be of sufficient length and should allow the “arrow” to turn freely.<\/p>\n
If the wind and iron objects do not interfere, then it will be located in the north-south direction.<\/p>\n
In cases where the compass is out of order, it is important to preserve its arrow. Having planted it on a needle, thorn, or in extreme cases, on a fish bone, we can always determine the direction to the north.<\/p>\n

To make a compass<\/strong> that can be carried, it is enough to make a case for it from available materials at hand.<\/p>\n
Based on the materials of the network (where I found it, I don't remember. -Chesselo !! But I thank the author, my notes)
\nIt was not for nothing that I put this idea in the section for hunters and fishermen, if you like to travel, like to pick mushrooms or berries in the forest, then you have a compass is simply necessary, since without it it is very easy to get lost. Of course, you can buy a compass in a store, but I suggest making it yourself, try to see how simple it is.
\nFirst of all, you need a round box, preferably with a lid. Use a metal box, such as a shoe polish. Anneal the iron box – heat it red-hot in the stove or on the stove and let it cool slowly. Then remove the scale from it and paint with nitro paint. Using a compass, draw the bottom on the cardboard along the inner diameter of the box. Cut it out and make a hole with a diameter of 2 mm with straight edges, into which you fasten an ordinary linen button so that the blind hole of the button nipple is at the top.<\/p>\nAccording to Figure 4, make a compass card out of thick paper; paint it with watercolor paint and cut it out. Glue the card to the prepared bottom, and place the bottom in the box. Also make the side of cardboard and, having greased it with glue, install it tightly into the jar, pressing the card to the bottom of the jar.<\/p>\n
The side should be 5-6 mm lower than the top edge of the can or rim. Then cut a circle out of thin plexiglass along the diameter of the can – the compass glazing; make a hole in the center of the circle and fasten the second linen button to it so that the blind hole of the button is at the bottom. Instead of plexiglass, you can take any transparent film or use photographic film, having previously washed off the emulsion from it.
\nHaving installed the glazing on the side, secure it from above using a spring ring made of steel wire. Linen buttons installed on the bottom and glazing serve as thrust bearings in which the axis with the compass arrow will rotate.<\/p>\nThe assembly of the compass parts is shown in Figure 5. Based on the height of your box, determine the height of the arrow axis. The axle is made of wire that could rotate freely in thrust bearings. File the ends of the axle carefully with a file and grind it with a block for the point of the knives.<\/p>\n
Transfer the arrow to the tin, cut it out, put it on the board, set the awl in the center of the arrow and, lightly hitting the awl with a hammer, punch a hole under the axle so that the axle fits tightly into the hole of the arrow. Take the axis with the arrow in your fingers and, lightly holding it, check that the arrow is balanced.<\/p>\n
If any end of the arrow outweighs, file it with a file. After the arrow is balanced, it must be removed and magnetized. First, at one end of the arrow, scratch the letter N with the tip of an awl, then take a magnet (Fig. 2) and draw its south pole (it is colored red) several times from the middle of the arrow to its end with a mark. Then with the north pole (it is colored blue) do the same with the other end. And so repeat several times.<\/p>\n
To magnetize, you can use magnets from loudspeakers of old receivers, tape recorders or televisions. They have the shape of a ring, so first this ring must be carefully broken with a hammer and chisel into several parts.<\/p>\n
Now place the arrow on the axis, and by holding the axis vertically in your fingers, you will see how it immediately takes a certain position. No matter how you change the position of the arrow, it will take the same direction. The end of the arrow, which is marked with the letter N, will always point to the north, and the other to the south. Now install the axle in the bearings – and the compass is ready. That's all there is to it.<\/p>\n
Situations when you may need a compass are different: you get lost in the forest, determine the north-south in the apartment, put furniture in Feng Shui. But, as always, at the right moment, there is not something important “at hand”, in this case a compass. What to do? Make it yourself. Below we will tell you how to make a compass and what you need for this.<\/p>\n
Making a compass at home<\/h3>\n
You can make two types of compasses – on water and on a string.<\/p>\n
For the first option, we need: a needle, a magnet, polystyrene, a wide glass container with water (a deep plate).<\/p>\n
- \n
- We make a compass arrow. We insert the needle into the foam so that both ends look out of it. At the same time, our arrow must keep exactly on the water, without turning over, that is, it is necessary to clearly find and establish the center of gravity.<\/li>\n
- We lower the arrow into a container with water. It will start spinning and after a while will stop, the magnetized end will point to the north.<\/li>\n<\/ul>\n
For the second option, we need a magnet, a needle, thread, scotch tape, a piece of paper, a pencil, scissors and a glass container (a 3 liter jar is suitable).<\/p>\n
- \n
- We magnetize one end of the needle.<\/li>\n
- Insert a needle into a piece of paper.<\/li>\n
- We glue the thread to the paper with tape, fix the other end of the thread on a pencil. Equalize the center of gravity of our arrow.<\/li>\n
- We lower the arrow into the jar, and put the pencil on the support (the neck of the jar).<\/li>\n
- The arrow will start spinning and the magnetized tip of the needle will point north.<\/li>\n<\/ul>\n
Now you know how to make a do-it-yourself compass at home<\/p>\n
Making a compass in nature<\/h3>\n
For this we will use the materials at hand. Of course, it is advisable to go on hikes, to hunt for mushrooms, put a wire or a nail, a piece of thread and a magnet in your pocket, but if some of this is not there, it doesn\u2019t matter. We propose to consider two options for creating compasses in extreme conditions.<\/p>\n
First: we need something small, metal. This can be a needle, a piece of wire, or a nail. Now we need to magnetize one of its ends, how to make a detail in a compass, the most important one – an arrow, if there is no magnet? You can magnetise a metal object by rubbing it. Rub it on your hair or woolen clothing. Now we attach a thread to our arrow. Be sure to find the center of gravity and balance the wire, otherwise the result will be incorrect. The length of the thread must be at least 40cm. We take the second edge in our hands or tie it to a stick and set it on a support. After our arrow spins and balances, the magnetized edge will point accurately to the north.<\/p>\n
For the second option, we need a hole with water or a bowl. We magnetize one end of our “arrow”. We take a leaf of a tree or a piece of bark and put it there. We put all this in a puddle and see where the tip of the arrow points. There will be north.<\/p>\n
As you can see, making a compass is not difficult in any situation, you just need to be smart. You can experiment at home first. If something goes wrong, we type in a search engine: how to make a compass – video, and watch. Now, for sure, there are no questions left.<\/p>\n
A device made of a needle and water<\/h2>\n
After the needle is finished, mark the magnetized end with any color and start building your home compass. Pour water into a bowl. Place the needle on the foam floating on the surface of the water. Place the bowl on a stable surface. You will see that the needle of your homemade compass rotates, pointing with the magnetized end to the north.<\/p>\n
