Where does the red end of the compass point?

The red end of the compass points to the north of the earth. This is because the compass made now is unified according to international standards, and the red end of the magnetic needle is the N pole of the magnetic needle, that is, the North Pole.

The predecessor of compass is Sina, one of the four great inventions in ancient China. The red pointer refers to the north.

The name of the compass makes people think it points to the south, but the red pointer actually doesn't point to the south at all.

There is a magnetic field around the earth. The magnetic induction line points from the south pole to the north pole. In a magnetic field, like-minded people repel and opposite-minded people attract, while the red pointer of a compass is actually the south pole of a magnet.

Extended data

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.

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 the invention of China. According to ancient mine records, it first appeared in the Cishan area during the Warring States Period.

Compass is the result of China ancient working people's understanding of magnet magnetism 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.
