The earth is a big magnet. The poles of the earth are close to the geographical south pole and the geographical north pole respectively. Magnets on the surface of the earth, when the compass can rotate freely, will indicate the north and south because of the nature that like-sex magnets repel and opposite-sex magnets attract.
The application of compass in navigation has greatly promoted the great geographical discovery and maritime trade. The invention of the compass originated from the study of how the ancient people in China oriented, and also showed that the ancient people attached importance to how to orient. Therefore, the compass is known as one of four great inventions of ancient china.
