How to make a compass? How to do it with a compass

Make your own compass.

Materials: needles, candles, wire, cold water, transparent plastic bottles, iron awls, fine wooden sticksHow to make them:

1 Wrap the sewing needle around the wire and burn it in a fire, then put it in cold water to cool immediately. You have to remember that when dipping, you must make the needle in a north-south direction, so that the needle can become a small magnetic needle. Also, you have to be careful, don't get hot!

2. Cut off the mouth of the plastic bottle, pierce a hole in the bottom ** with an iron cone, and then tie one end of the thin wire to the middle of the small magnetic needle, and then pass the wire through the hole. Invert the plastic bottle so that the small magnetic needle hangs in the middle of the bottle. Make the small magnetic needle slowly stand still, and then you will find that one end of the small magnetic needle points to the south, and the other end refers to the north.

Prepare a piece of styrofoam (foam) about the size of a peanut.

A sewing needle.

A basin of water. A magnet.

The sewing needle rubs the magnet 30 times.

Then thread it into the middle of the styrofoam.

And then put it in the basin, and the needle will point south.

How do you rotate the sewing needle The sewing needle will still turn in the direction of the south

Materials: needle, magnet, small piece of plastic foam, small bowl of water.

Method: 1 Rub the needle on the magnet for ten minutes to make the needle magnetic, and then insert the needle into a small piece of plastic foam (the plastic foam should be just enough for the needle to float on water).

2 Put the plastic foam with the needle in it in a small bowl of water, and you can see that one end of the small magnetic needle points to the south and the other end points to the north. (If you want to go out, you can install it according to the second step of the upstairs).

The magnetized needle is placed on the water.

Compass manufacturing method:Prepare the tools Ingredients: embroidery needles, water, bowls or cups as long as they can hold water, magnets, pens.

1. Prepare the tools you need.

2. Rub the magnet back and forth on the embroidery needle several times.

3. After rubbing, insert the needle into the cut paper.

4. If necessary, you can write the north-south direction on the paper.

5. Put the paper in the bowl filled with water, and the compass is made here.

The compass, called Sinan in ancient times, is mainly composed of a magnetic needle mounted on an axis, the magnetic needle can rotate freely under the action of the natural geomagnetic field and remain in the tangent direction of the magnetic meridian, the south pole of the magnetic needle points to the geographical south pole (magnetic field North Pole), and the direction can be discerned by using this performance.

It is commonly used in navigation, geodesy, travel and military applications. There are three types of components for the compass that physically indicates the direction, namely the Sinan, the compass and the magnetic needle, all of which belong to Chinese inventions. According to the records of the "Ancient Mine Record", it first appeared in the Cishan area during the Warring States Period.

The compass is the result of the understanding of magnetism by the ancient Chinese working people in long-term practice. As one of the four great inventions of ancient China, its invention has played an immeasurable role in the development of human science and technology and civilization. In ancient China, the compass was first used for rituals, ceremonies, military affairs, divination and feng shui to determine directions.

Materials: a slightly larger non-transparent cap, a slightly smaller transparent cap, steel needle, sorbet stick, lighter, magnet, super glue.

Steps: 1. Cut the sorbet stick slightly shorter than the steel needle;

2. Rub the steel needle from the magnet for more than 20 times or wrap the steel needle with iron wire, then put it in the fire to burn red, and then immediately immerse it in cold water to cool;

3. Use super glue to stick the steel needle and the ice cream stick in the same direction;

4. Fill a slightly larger bottle cap with an appropriate amount of water;

5. Put the glued steel needle and sorbet stick into the cap of the bottle filled with water;

6. Put a slightly smaller transparent bottle cap on it and glue it with super glue;

7. When the compass stops, add a magnetic declination angle clockwise, and mark the north and south levels.

1. First of all, you need to prepare a pin, just an ordinary pin, or a small iron nail.

2. Then we prepare a capsule, pour the medicine inside, just the capsule shell.

3. Then take a bowl and hold a bowl of water for later use.

4. Then rub the prepared pin on our hair and rub it repeatedly for about a minute. You can also rub on the magnet, which is more effective and will make the iron thing magnetic, which is needed for the compass.

5. Put the pin through the capsule, put it in the water, and make a water float guide, and the compass will be successful, which is also a very ancient method. You can take out the compass of the mobile phone to compare, and the position pointing is basically correct.

Making a compass is a very fun DIY activity, and many people enjoy making their own. Here's a simple and practical way to make a compass:

Materials needed: magnets, plastic plates, paper, scissors, pencils, rulers, tape.

Steps: Draw a circular mold ruler board on white paper, about 15 cm in diameter. Then cut it off.

Place the template on a plastic plate and secure the position. Use a pencil and ruler to trace a circle of the same size from the template and cut it off.

Place the cut round piece on a flat spot and magnetize it using a magnet.

Wait for the disc to be completely stabilized, and mark the direction point and direction character around it. You can choose to start directly above, which is North, and then mark east, south, west, and so on.

At this point, you have completed a simple compass. You can paint its surface with colors, mark out the scale and other details to make it more beautiful and functional.

Precautions: In the process of doing, do not over-magnetize the round magnet, otherwise it may affect the accuracy of the compass, maintain an appropriate degree of magnetization.

You need to be very careful when marking with a ruler and pencil, as they are essential to the correctness of your compass and make its surface more beautiful.

Particular precision and rigor is required when defining the direction of your thoughts to ensure that the compass you make is accurate and reliable.

The above is a simple and practical compass DIY production method. As long as you draw patiently and apply the above method steps, I believe you can easily make a very useful compass.

Within. The compass is an extremely important tool that helps us determine direction quickly, accurately and easily. So, how do you make a compass?

In the first step, you need to prepare some raw materials to make a compass, such as magnets, iron plates, glass dials, hands of the compass, tubular iron, iron wires, batteries, circuit boards, etc.

In the second step, the magnet and the iron plate are welded to make them fit snugly, and the center of gravity is placed in the standard position.

In the third step, attach the glass dial and compass hands and fix them with screws.

In the fourth step, the tubular iron and iron wire are soldered to the circuit board, the battery and the circuit board are placed on the iron plate, and the upper pointer is connected.

In the fifth step, place the pointer, battery, and circuit board on the magnet so that the pointer is pointing in the direction in front of you, and the compass is complete.

After the above steps, a simple compass is made in this way. The making of a compass is not a simple matter, and it is necessary to understand the principle of its making and have patience to complete a compass.
