Hysteresis loops can be used to understand which parameters of the magnetic material
If your material is relatively deep, you can see from the material hysteresis loop basically the type of material, phase of the situation And chemical composition of comparison, we can see the grain of the material, some of the material can know the internal parameters such as defects and other parameters Saturation magnetic induction, coercivity, residual magnetic induction, etc, the area surrounded by the hysteresis loop represents the energy consumed by the magnetization cycle of the ferromagnetic material, which is often converted into heat energy and is consumed Different ferromagnets have different shapes and ridges, and the hysteresis loops of different shapes have different applications For example, the permanent magnet material requires a large coercive force and a large remanence; the soft magnetic material requires a small coercive force; the core in the memory element requires an appropriate low
Hysteresis loop is also divided into two kinds of normal temperature and high temperature
Hysteresis loop can know the saturation magnetic flux of the material Bs, remanence Br, coercivity Hc
