A. Even if a ferromagnetic material such as iron or ferrite is magnetized, the saturated magnetic flux density is achieved, and the current is decreased so that the magnetic field is returned to zero, there is still magnetization remaining in the material. This magnetic flux density is known as residual magnetic flux density. It is an indicator of magnetic coercive force as well as the size of the magnetic power of permanent magnets.
