Magnetic materials are now mainly divided into two categories, one is soft magnetic materials, the other is hard magnetic materials (permanent magnetic materials). Soft magnetic material: high permeability, easy to be magnetized and easy to demagnetize. In the saturation state, the magnetic flux is large, the coercivity (Hc) is small, the total area of the hysteresis loop is narrow and long, and t...
Have you heard of isotropic magnets and anisotropic magnets? What are the connections and differences between them? In simple terms, magnetic materials fall into two categories. One is an isotropic magnet, which has the same magnetic properties in any direction and can be magnetized in any direction. The other type is anisotropic magnets. Anisotropic magnets have different magnetic properties in d...
