What are permanent magnet materials?

Permanent magnetic materials, also known as "hard magnetic materials", refer to materials that can maintain a constant magnetic property once magnetized. In practice, the permanent magnet material works in the second quadrant demagnetization part of the hysteresis loop after deep magnetic saturation... read more

Characteristics of magnetic materials

Magnetic materials have magnetically ordered strong magnetic substances, and broadly include weak magnetic and antiferromagnetic substances that can apply their magnetism and magnetic effects. Magnetism is a basic property of matter. Substances can be divided into diamagnetic, paramagnetic, ferromag... read more
