The Nature Of The Role Of The Magnet

- Apr 02, 2018 -

Magnets have two polarities, magnetic north pole N, magnetic south pole S, and are still N pole and S pole. A single magnetic pole cannot exist. At the same time, the magnet has directivity. If you hang a magnet, you will find that its south pole points to the geographical south pole, and the north pole points to the north pole.

The magnetic poles interact with each other, and the magnetic poles of the same name repel and the magnetic poles of different names attract. There is a substance around the magnet that deflects the magnetic needle. This substance is physically called a magnetic field. The distribution of the magnetic field is usually represented by magnetic lines of inductance.
