A magnet is a substance that generates a magnetic field and attracts or repels objects. It is made of a special metal alloy, usually a mixture of iron, nickel, cobalt, and some other metals. Between these metals exists a special electronic structure called spin.

When a magnet is heated or subjected to a certain force, it loses its magnetism. This is due to the fact that the magnetism is due to the way electrons are arranged in the magnet crystal, which is changed by the influence of temperature and force.

In a magnet, there are two polarities: North and South. When two magnets are brought close together, their north poles attract each other, while their south poles repel each other. This interaction is produced by a magnetic field. Magnetic fields are generated by the movement of electric charges, so magnetism is closely related to electricity.

Magnets are widely used in industrial and scientific applications. The most common are electric motors and generators. Both motors and generators rely on the force of magnets to turn and thus generate electricity. Magnets have many other applications, such as magnetic resonance imaging, magnetic cards, television and computer monitors, and more.

In addition, magnets are also used to heal diseases. Magnetic therapy is believed to help the body restore balance and health. Magnetic beads used in massage therapy are also an application of magnets.

Overall, magnets are a versatile substance that can be used in a variety of fields, from generating electricity to medical treatments.

There are five types of magnetism: ferromagnetism, antiferromagnetism, ferrimagnetism, diamagnetism, and paramagnetism.

The strongest is ferromagnetic. Iron, cobalt and nickel are ferromagnetic, and the ferromagnetism of rare earth elements is the strongest. Cobalt and nickel are rare earth elements, so their magnetism is relatively strong.

But the strongest magnetism in production application is NdFeB material. Then Samarium Cobalt, then Alnico.

Magnetic domain alignment is the key.
