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.
