How to make a real compass without water. How to make a compass with your own hands at home and outdoors. Making a compass in nature
It happens that you need to know exactly which side is south and which is north. At home, this can be useful when setting up an antenna, but travelers cannot do without such knowledge, especially in the wild. Of course, the easiest way is to use an ordinary compass. What to do if it is not at hand? How to make a compass at home and outdoors? It turns out it's very simple. You won't need special devices- only improvised materials that every home has, or can be easily obtained in the forest.
at home
1. In order to make an indispensable tourist attribute, you need a needle, a small piece of foam rubber and a mug of water. To begin with, you should take foam rubber, approximately 3x3 centimeters. We will need it so that the needle floats on the water and does not sink. We pierce the foam rubber with a needle in the center and place simple design in a mug of water.
2. In order for it to become a real compass, it remains to magnetize one tip of the needle. Finding a magnet in an apartment is very easy. It is in the headset, holding the doors or in the speaker music center. To demagnetize the needle, just bring one of its tips to gas burner and hold over the fire for 20 seconds. Thus, the magnetized tip of the needle will show us north, the demagnetized tip will tell us where south is. We place our structure in the water again.
3. To understand where north is and where south is, stand facing the direction of the needle. Remember which window the sun shines through in the morning (this will be the east), respectively, the sun sets in the opposite direction - this will be the west. Now stand along the needle so that the east is on the left and the west is on the right. This will put you facing south and your back to north.
How to make a compass in nature
Sometimes when hiking, for example in the forest, it is important to know the exact direction of the path so as not to get lost. It turns out that it is also easy to understand where is north and where is south, using available means. Let's look at two options for how to create your own compass in extreme conditions.
1. For the first option you need to find something metal. Anyone will do nail, wire or needle. To magnetize our arrow, just rub it on your hair. Next, the nails need to be tied to a thread or fishing line and hung on a static surface (for example, a tree branch). It is important that the length of the thread is at least 40 centimeters, otherwise the result will be inaccurate. Now the arrow will accurately point with its magnetized end to the north. You already know how to determine other directions.
2. For the second option you need a bowl of water. Magnetize one end of the arrow and place it in a bowl, placing it on a piece of bark. The arrow will definitely tell you where north is.
So now you know how to make a compass in any situation. This procedure will not take much time even in conditions modern apartment, even in a dense forest. All you have to do is show a little ingenuity and find suitable materials, create a simple device with your own hands, and you will always know exactly in which direction you should move. Now you are not afraid of any troubles while traveling.
We will need:
Any container, except metal, filled with water (metal ones are not suitable, as they will distort the magnetic field).
In order to make a compass, we take floating material and cut out a platform for a needle from it. The main parameters of the piece are the smaller the better, but the needle should not be above the surface of the water.
As you already understood, the needle acts as an arrow. In order to be able to determine the cardinal directions using our homemade compass, one end of the needle must be magnetized. If you have magnets at hand (they are present in the speakers of the player, receiver, electric motors, etc.), then you can magnetize the needle-arrow with their help. 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. So, the arrow is ready. Its magnetized end will point to Serer, and its non-magnetized end will point to the South.
We attach the needle-arrow to the float. The most convenient way is to carefully pierce the float with a needle along the axis of symmetry (if the float is voluminous). This fastening is simple and at the same time reliable. Next, place the float with the needle in a container of water so that they do not touch the walls of the vessel. The compass is ready with your own hands, all that remains is to calibrate it.
If you know which tip of your needle was magnetized and which was not, you can immediately judge where north is by the position of the magnetized tip. If you don’t know, then the following facts will help you determine where North and South are: the place where the sun rises and where it sets (Sunrise-East, Sunset-West) or the position of the polar star. Using these signs you can easily calibrate your homemade compass.
Sometimes, apart from a needle, there is no floating material at hand. In this case, to make a compass, you can pick any leaf that can hold the needle above the water. Again, the smaller it is, the better.
I made a similar compass, but at home.
1). The sharp end of the sewing needle rubs against the magnet.
2). I pierced the wide cork of a bottle (or a thermos) with a needle so that it came out from the sides and not from the ends of the cork.
3). I lowered the stopper with the needle into a container of water so that it did not touch the walls of the container.
In the forest you can use a puddle of water.
The cork became a kind of float in the water and it turned out that the sharp end of the needle began to point north.
I also tried to do something similar without using water and a magnet.
1). The sharp end of the needle is rubbed artificial fabric from clothes that have static on them.
2). I tied a thread to the center of the needle so that the needle hung evenly - neither end outweighed the other.
3). I put the thread and needle into the jar (it might be windy outside).
The result was the same - the sharp end of the needle began to point north.
In an emergency, you can navigate the terrain without a compass. For example:
On a clear night, according to the stars (polar star for the northern hemisphere, southern cross for the southern hemisphere).
Moss grows on tree trunks, stumps, and stones on the north side.
The tree crown is more luxuriant on the south side.
Snow does not melt for a long time on the northern side of the slopes of ravines, trees, large stones, any objects creating a shadow.
By using wristwatch with arrows on a sunny day. Hour hand point towards the Sun. Divide the angle formed between the hour hand and the number 1 in half and this line will be an indicator of the direction to the South. The only condition- this angle must be less than 90 degrees.
And of course, you can build a primitive compass from scrap materials. To make it you will need a steel object ( sewing needle, nail, screw or piece of wire) and any floating object in the water into which an object made of steel can be stuck or attached to it (a piece of foam plastic, a piece of cardboard paper or torn from a tree, a cork stopper from a wine bottle or thermos, a sliver of wood, and finally and of course same container with water (not steel) in which you need to place a steel object attached to a floating object in such a way that they do not drown together. The floating steel object is oriented in the South-North direction. The meaning of all this is that steel objects have weak magnetization from magnetic field land sufficient for use as a primitive compass. The only difficulty that may arise is which end points to the North and which to the South. In this matter, only the Sun can help during the day, at night - the stars or the Moon.
A small steel needle can be made to float on the surface of the water on its own. To do this, you need to rub it a little with your fingers (the oilier your fingers, the better) and carefully place it on the surface of the water. If this procedure is carried out with due care, it will float held by the forces of surface tension of the water.
The children's compass shows that the point of the needle is directed towards the South. No manipulations were performed with the needle (such as magnetizing it with a magnet or heating the tip).
Making a mini compass at home is not big problem. The main thing is to make sure that the magnet, which plays the role of the arrow, rotates with minimal friction. Typically, a magnetic needle is mounted on a point, which is essentially a bearing that provides minimal friction when turning the needle. Another option could be a magnetic needle floating on the surface of the water. This is exactly the option that was used by the author. Of course, for one-time use, you can limit yourself to a piece of foam pierced with a pin or a piece of an unbent paper clip. But for regular use You can make something more fundamental, however, also at minimal cost.
Round elements are used as body elements. plastic caps from dairy products, with a diameter of 31 and 28 mm, the height of the lids is 10 mm. The lids fit perfectly into each other, forming halves of the body.
Actually, the role of the magnetic needle in the device is a ferrite magnet in the shape of a 10x4x4 mm parallelepiped; in addition, you will need two short strips of 10 x 4 mm tin. The magnet was taken from an old reed keypad. For reliable fastening in the case, a holder is cut out of packaging plastic, packaging scraps are selected that have a groove of the required width for installing a magnet.
Tin plates are bent in the manner shown in the photo, so that they are securely magnetized to the ends of the magnet.
In the lid of a smaller diameter we install one half of the holder, cut to fit.
Place the magnet.
Place the top half of the holder.
Using Moment glue we connect the halves of the body.
Now, using another compass, we determine the poles of the magnet and apply the appropriate markings.
Floating on the surface of the water, the compass copes with its tasks quite well.
A group of compasses can demonstrate the domain structure of a ferromagnet.
Summarize
Of course, this design is not a full-fledged compass; its main purpose is to demonstrate the behavior of a magnet in an external magnetic field, to demonstrate. Naturally, if it is possible to demonstrate this more easily on compasses, but in the absence large quantity compasses, this option is also suitable. Author - Denev.
Discuss the article HOW TO MAKE A COMPASS WITH YOUR OWN HANDS
Sometimes on long trips there is an urgent need to correctly determine the cardinal directions. It may even happen that the life and health of the expedition members will depend on this. If you have a compass, it doesn't matter. What if it fails or is lost? Then the options are: determine the cardinal directions by the stars, the sun, signs, or make a primitive compass yourself. I just want to tell you how to make a compass yourself, using only available material. We will look at several variations of such homemade devices.
DIY compass made from a needle and a container of water
- Glass or ceramic container with fresh water(metal ones are not suitable, as they will distort the magnetic field).
- Needle
- A piece of floating material (cork, polystyrene, foam rubber)
Assembling a homemade compass
Cut off a small piece of floating material. The most important thing is that it is of such a size as to ensure the buoyancy of the needle attached to it and at the same time that it is of such a size that the forces of surface tension of the water and the drag forces are negligible - this is necessary to ensure the accuracy of the readings.
Our needle will serve as 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, electric motors, etc.), then you can magnetize the needle-arrow with their help. 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, you understand why this happens). So, the arrow is ready. Its magnetized end will point to Serer, and the non-magnetized end will point to the South.
We attach the needle-arrow to the float. The most convenient way is to carefully pierce the float with a needle along the axis of symmetry. This fastening is simple and at the same time reliable. All that remains is to simply place the float with the arrow in a container of water so that the walls of the container do not interfere with the rotation of the arrow. The compass is ready, all that remains is to calibrate it.
If you know which tip of your needle was magnetized and which was not, you can immediately judge where north is by the position of the magnetized tip. If you don’t know, then the following facts will help you determine where North and South are: the place where the sun rises and where it sets (Sunrise-East, Sunset-West) or the position of the polar star. Using these signs you can easily calibrate your homemade compass.
DIY compass without using liquid
- Needle or blade safety razor
- Transparent bottle
- Thin thread or fishing line
We make a compass needle and magnetize it, as described in the previous instructions. To make an arrow, you can use a needle or a safety razor blade. You can also make an arrow from half a razor blade.
We calibrate the resulting compass using the method described in the last paragraph of the previous instructions and obtain a device ready for use.
As you can see, making a compass yourself is not that difficult. On the one hand, we looked interesting solutions, and if you dig deeper, it becomes obvious that we have expanded our knowledge base extremely useful information! Happy travels, friends.

How to make a compass?
There are different situations when you may need a compass: lost in the forest, determining north-south in an apartment, arranging furniture according to Feng Shui. But, as always, at the right moment, something important is not “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.
Making a compass at home
You can make two types of compasses - on water and on string.
For the first option we will need: a needle, a magnet, polystyrene foam, a wide glass container with water (deep plate).
- We draw a magnet along one of the tips of the needle, 20-30 times in one direction. This is how we magnetize it.
- Making a compass needle. We insert the needle into the foam so that both ends stick out from it. At the same time, our arrow must stay level on the water without turning over, that is, we must clearly find and establish the center of gravity.
- We lower the arrow into a container of water. It will start spinning and after a while will stop, the magnetized end will point north.
For the second option, we will need a magnet, a needle, thread, tape, a piece of paper, a pencil, scissors and a glass container (a 3 liter jar will do).
- Magnetize one end of the needle.
- Insert a needle into a piece of paper.
- We glue the thread to the paper with tape, and fasten the second end of the thread to a pencil. Let's equalize the center of gravity of our arrow.
- We lower the arrow into the jar, and place the pencil on the support (neck of the jar).
- The “arrow” will begin to spin, and the magnetized tip of the needle will point north.
Now you know how to make a compass with your own hands at home.
For this we will use available materials. Of course, when going hiking, hunting, or picking mushrooms, it is advisable to put a wire or nail, a piece of thread and a magnet in your pocket, but if you don’t have any of these, it doesn’t matter. We propose to consider two options for creating compasses in extreme conditions.
First: we need something small, metal. This could be a needle, a piece of wire or a nail. Now we need to magnetize one of its ends, how can we make a part in a compass, the most important one – the arrow, if there is no magnet? Magnetize metal object possible by friction. Rub it on your hair or woolen clothing. Now we tie 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 place it on a support. After our needle spins and balances, the magnetized edge will point accurately to the north.
For the second option, we need a hole with water or a bowl. We magnetize one end of our “arrow”. Take a leaf of a tree or a piece of bark and put it there. We lower it all into the puddle and see where the tip of the arrow points. That's where the north will be.
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, type in a search engine: how to make a compass - video, and watch. Now, for sure, there are no questions left.
When going on a trip, you should think about all the outcomes of your vacation. Sometimes mysterious, dense, alluring forests, mountains, rocks call us deeper into them. And we follow this call of nature without noticing that we have moved far from the entrance, and you don’t know how to get out! Or you just need to arrange the plants according to Feng Shui, and for this you need to determine the cardinal directions, but what to do if you don’t have a compass at hand? In this article we will tell you how to create a wonderful compass at home, according to the definition of the parties, different ways. So, let's begin!
DIY compass
Compass on a thread and a needle
In fact, making a compass using needles and threads is very simple and most importantly effective! To begin with, take an ordinary needle; everyone has one somewhere at home. Then rub it properly with a magnet so that it becomes magnetized. The next step is to take any thread. If you find yourself on a hike and don’t have a spool with you, you can tear one from any clothing. Next, thread the needle and tie it in a knot. Be careful, it is advisable not to take it too tightly in your hands, it can transfer the charge to you and thereby become demagnetized.
Place it horizontally and observe. One end of the needle will point north and the other end will point south. On the right and left sides there will be the eastern and western sides of the world. Mark which end showed the north, this can be done with the help of brilliant green, iodine, which travelers always have. That's all. You can safely determine the cardinal directions using it, just like a standard compass.
How to make a compass from a needle and water
One more the easy way The method for making a compass is with a needle and water. This is a very handy method that allows you to make 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 using a magnet. Rub the needle on it, but not the whole part, but only one end. The other end must be uncharged. To discharge it, you can hold it over the fire, this will neutralize the charge. If you don’t have a special magnet, you can use any, even the smallest ones, like those on the refrigerator. Or use silk, it charges objects perfectly like no other.
The next step is to mark in color which side is magnetized so as not to confuse the sides. You can mark it with any paint or brilliant green, iodine or any other impurities. Next comes the most interesting part, pour water into the bowl, place the needle on a stable surface that will float on the water (pinoplast, wine cork, plastic, and any other objects that float on the surface of the water). Next you need to observe. The arrow will turn towards 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.. This is the way! Very light and effective in any terrain.
Compass made from a paper clip
So, to make a compass from a paper clip, you need to properly charge it. This can be done using a well-known magnet, or remember seventh grade physics and use silk. Rub it to recharge it. Next, you need to carefully place the paper clip on the cardboard or paper surface and lower it into the water. Make sure that nothing interferes with the movement of the paperclip. Eliminate all drafts and gusts of wind. It is also worth using a small piece of paper surface to avoid collision with the bowl of water. That's all, the compass is ready. If you did everything correctly, he will show you the way to the north. Bon Voyage!
How to make a homemade compass
In order to make a homemade compass from cardboard, you need to cut out a circle. You need to draw the drawing correctly to get an even circle. The next step is to charge the needle using a magnet or using a lye by rubbing it against these objects. Or you can use a paper clip rather than a needle, the principle is the same. Next, insert a needle or wire into the cardboard. We install it and watch its movements. It should point towards the north. Next, we plot the cardinal directions to the south, in the appropriate order. That's it, the cardboard compass is ready! This can be given to a child for learning orienteering, your child will be happy!
How to make a cut and a hole in a compass
How to make a compass in 3d? To do this you need to draw correct drawing. There should be several such drawings from different sides. Top view, left side and interior. This is all done using different programs, which are made specifically for these purposes. They are quite easy 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.
