What are the properties of magnets?
The composition of the magnet is iron, cobalt, nickel and other atoms, the internal structure of the atom is relatively special, has its own magnetic moment. Type of magnet: Shape magnet: square magnet, tile magnet, special-shaped magnet, cylindrical magnet, round magnet, round magnet, magnetic bar magnet, magnetic frame magnet, property magnet: Samarium cobalt magnet, neodymium magnet, ferrite magnet, aluminum nickel cobalt magnet, iron chromium cobalt magnet, industrial magnet: magnetic components, motor magnet, rubber magnet, strong magnet, plastic magnet, etc.
Magnets are divided into permanent magnets and soft iron. The combination of permanent magnets and strong magnetism causes the spins of magnetic materials to align in a fixed direction with the angular momentum of electrons. Soft magnet with current (also a method of adding magnetic force) and so on. When soft irons are removed, they slowly lose their magnetism.
Magnets can generate magnetic fields and attract ferromagnetic materials such as iron, nickel and cobalt.
The midpoint of the bar magnet is suspended by a thin wire. When it is at rest, its ends will point south and north of the Earth. The end pointing north is called the North or N pole, and the end pointing south is called the guide or S pole.
If you think of the Earth as a big magnet, the Earth's magnetic North Pole is the guide pole, and the magnetic South Pole is the North Pole. With magnets, homosexuals repel and opposites attract. So the compass repels the South Pole, the North Pole repels the North Pole, and the compass attracts the North Pole.
