Where is the compass? What do n, w, e and s mean?

W stands for the West, E stands for the East, S stands for the South, and N stands for the North, although it is a compass.

But in fact, most of the compasses we buy refer to the north needle. Under normal static state, it should point to N or the north of our country. If you are in the polar region, the compass will fail and you don't know which direction to turn.

When WESN is combined, it happens to be news, and news is news from all directions! If you remember the news, then you will remember that the compass points to the north.

Compass is the result of the understanding of the magnetism of objects by the working people of ancient Han nationality in long-term practice. As one of four great inventions of ancient china, its invention has played an inestimable role in the development of human science, technology and civilization. In ancient China, the compass was first used for rituals, etiquette, military affairs and divination, and to determine the orientation when looking at geomantic omen. 1 1 At the end of the century or at the beginning of the 2nd century, China ships began to use compasses for navigation.

Compass is a simple tool to judge the direction. The predecessor of compass is Sina, one of the four great inventions in ancient China. The main component is a magnetic needle that can rotate freely on the shaft. The magnetic needle can be kept in the tangential direction of magnetic meridian under the action of geomagnetic field. The north pole of the magnetic needle points to the geographical north pole, which can be used to identify the direction. It is often used in navigation, geodesy, tourism and military affairs. There are also bands and movies of the same name.
