Compass is the result of China ancient working people's long-term understanding of the magnetism of magnets. At normal rest, it points to the south. Its main component is the magnetic needle installed on the shaft, which is often used in navigation, geodesy, travel and military affairs.
The identification method of the compass is relatively simple, and the specific steps are as follows:
1. Turn in the same place with a compass until the red pointer coincides with the north. This time is the southeast and northwest direction of the actual position;
2. Put the compass flat so that the pointer can rotate freely, and rotate the compass housing so that the pointer is aligned with the scale in the north-south direction;
3. Keep the pointer on the scale in the north-south direction and rotate your body so that your eyes and the center of the compass are in a straight line. The direction you want to see on the scale of the compass is the direction you want to find. The "n" of the compass refers to the North, which is the first letter of the English word north. "S" refers to the South, which is the first letter of the English word South.
What are the directions of compass N and S?
The main part of the compass is the magnetic needle installed on the rotating shaft. Under the action of natural geomagnetic field, the magnetic needle can rotate freely and keep in the tangential direction of magnetic meridian. Compass uses the earth's magnetic field to indicate the north, and uses the principle of magnetic field to repel the same polarity and attract the opposite polarity. Today, let's talk about what directions the compass N and S indicate.

Compass, called Sina in ancient times, is mainly composed of magnetic needles installed on the shaft. Under the action of natural geomagnetic field, the magnetic needle can rotate freely and keep in the tangential direction of magnetic meridian. The north pole of the magnetic needle points to the north pole, so this property can be used to identify the direction. It is often used in navigation, geodesy, tourism and military affairs. The invention of the compass with physical direction indication has three parts, namely Sina, compass and magnetic needle, all of which belong to China's hair.
0 There are the following letters on the compass, which respectively represent:
North line
South (south)
East: East.
Woman: Western.
Northwest: Northwest (Northwest)
Northeast: Northeast.
Southwest: Southwest.
Southeast.

Although it is a compass, in fact, most of what we buy refers to the north needle. When WESN was merged, it happened to be news. News refers to news from all directions. If you remember the news, you will remember that the compass points north.
