Magnetic materials are those in which a state of magnetization can be induced. Such materials create a magnetic field in the surrounding space. Some of the important magnetic properties are as follows:
- Permeability
- Coercive force
- Magnetic hysteresis
Permeability is the ratio of the flux density in a material to the magnetizing force producing that flux density.
Coercive force is the magnetizing force that is necessary to neutralize the magnetism completely in an electromagnetic field.
Hysteresis is that quality of a magnetic substance due to which energy is dissipated in it on reversal of its magnetism.
