How the poles of a magnet attract each other

A magnet has positive and negative poles, and there is a magnetic field around the magnet. When the different poles of two magnets are close to each other, the eddy current of the magnet will interact with the different-stage magnet, resulting in mutual attraction. When two magnets are near the same pole, they repel each other. Simply put, the mutual attraction and mutual exclusion of magnets is caused by the magnetic field in the magnet.

How the two poles of the magnet attract each other？

The composition of the magnet is iron, cobalt, nickel and other atoms, the internal structure of the atom is relatively special, itself has a magnetic moment. A magnet produces a magnetic field and has the property of attracting ferromagnetic materials such as iron, nickel, cobalt and other metals. When a bar magnet is suspended from its midpoint by a thin line, it will be stationary with its ends pointing north and south. The north-facing end is called the north or N Pole, and the south-facing end is called the south or S pole. This is the positive and negative poles of a magnet, a magnet in physics, “Opposite Poles repel each other, opposites attract,” said.

If you think of the Earth as a large magnet, the Earth’s magnetic North Pole is the South Pole, the magnetic south pole is the north pole. Between the magnet and the magnet, the same name magnetic Pole repels mutually, the different name magnetic Pole attracts mutually. So, the compass is repelled by the South Pole, the compass by the North Pole, and the compass by the North Pole. In fact, this phenomenon is mainly related to the magnetic field of the magnet.
