What are the parameters of magnetic materials in the hysteresis loop?
Different ferromagnetic materials have different shapes of hysteresis loops, and different shapes of hysteresis loops have different applications. For example, permanent magnets require large coercivity and large remanence; soft magnetic materials require less coercive force; ferromagnetic cores in memory elements require low coercive force.
The saturation magnetization and coercive force, residual magnetic induction and so on, surrounded by the hysteresis area, said ferromagnetic material magnetic cycle energy, this energy is often converted into heat which is consumed.
If your material foundation is relatively deep, you can basically see the type and phase of the material from the hysteresis loop of the material. Compared with the chemical composition, we can see the grain of the material, and some of the material can know the internal defects of the material.
The saturation magnetic flux density (Bs), remanence Br and coercive force (Hc) are known in the hysteresis loop. The hysteresis loop is also divided into two kinds: normal temperature and high temperature.
