Here are the details of the newsHere are1) Permanent magnet motor is divided into permanent magnet DC motor and permanent magnet AC motor.

Magnets sound familiar, everyone knows that magnets can absorb iron, many people have used it, but when asked about the specific application of magnets in daily life, it is difficult to generalize.

Permanent magnet material: permanent magnet material magnetized by external magnetic field does not disappear, can provide stable magnetic field to external space. There are four commonly used measuring indicators of Nd-Fe-B permanent magnets:

Summary of magnetic materials: magnetism is one of the basic properties of materials. Magnetic phenomena are associated with various forms of charge motion. Because the motion of electrons and spin in matter can produce a magnetic field of certain magnitude, magnetism is produced. All substances are magnetic. Nature can be divided into paramagnetic material, diamagnetic material, ferromagnetic material, antiferromagnetic material and ferromagnetic material according to the difference of magnetism. Among them, ferromagnetic material and ferromagnetic material belong to strong magnetic material, which are generally referred to as magnetic material.
