How does the compass look at the southeast and northwest?

The direction of the compass is north and south. Generally speaking, the northern end will be marked with eye-catching colors, and some compasses are marked with the south.

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 south pole of the magnetic needle points to the geographical south pole (magnetic north pole), and the direction can be distinguished by using this property.

As one of four great inventions of ancient china, the invention of compass has played an inestimable role in the development of human science and 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.

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.

Instructions for use of compass

Hold the compass correctly. Put the compass flat on your palm and your palm on your chest. This is the standard way to hold a compass when traveling. If you want to refer to the map at the same time, put the compass flat on the map, so the result will be more accurate.

Find the direction you are facing. If you want to guide yourself correctly, you must first be clear about your immediate direction. Look at the magnetic needle on the compass. The magnetic needle will not deflect back and forth only when it points to the north.

Turn the dial until the guide arrow and the magnetic needle are in a straight line, and then point to the north together, so that the guide arrow will tell you the direction ahead. If the pointing arrow lies between the north and the east, then you are facing the northeast.

Find the intersection of the pointing arrow and the dial. If you want more accurate results, you can carefully check the scale on the compass. If the pointing arrow points to 23 on the dial, then the direction in front of you is 23 degrees north-east
