What are the uses of magnetic materials？

The use of magnetic materials: Magnetism is one of the basic properties of matter. The phenomenon of magnetism is associated with various forms of charge movement, and the movement and spin of electrons inside the substance will generate a large and small magnetic field, thus generating magnetism. All matter is magnetic. Nature can be divided into paramagnetic substances, diamagnetic substances, ferromagnetic substances, antiferromagnetic substances, and ferrimagnetic substances according to different magnetic properties. Among them, ferromagnetic substances and ferrimagnetic substances belong to strong magnetic substances. Substances are collectively referred to as magnetic materials.

Magnetic materials are important basic functional materials in the electronics industry. They are widely used in industrial fields such as computers, electronic devices, communications, automobiles and aerospace, as well as daily necessities such as household appliances and children's toys. With the rapid development of the world economy and science and technology, the demand for magnetic materials is unprecedentedly broad.
