The meaning of permanent magnetic materials

- Nov 22, 2017 -

With a wide hysteresis loop, high coercivity, high remanence, once magnetized to maintain a constant magnetic material. Also known as hard magnetic materials. Practical, permanent magnet materials work in depth magnetic saturation and magnetization hysteresis loop after the second quadrant demagnetization.


Commonly used permanent magnet materials are divided into alnico permanent magnet alloys, ferrochromium permanent magnet alloys, permanent ferrite, rare earth permanent magnet materials and composite permanent magnet materials.
