Since every substance has certain magnetic properties within themselves, it is based on ability of magnetization that its standard is determined. They have a comparatively stronger magnetic field in comparison to magnetically soft materials.
The various magnetically hard materials are:
In comparison to magnetically soft materials that are simply suitable for electromagnets, these hard materials are used for making permanent magnets. The basic features that make these suitable for making these hard are:
Only when a particular substance matches all these contexts, it is known as magnetically hard material.
