Hard magnetic material

RRB JE EC 79 11 Q magnetic materials and Jointing of wires Hindi images madhu and shashi Q3

The magnetic materials that can retain their magnetism even after the removal of the external magnetic field, and are difficult to magnetize and demagnetize are known as hard magnetic materials.
The area of the hysteresis loop of hard magnetic material is large.
Due to the large area of the hysteresis loop, the hysteresis loss in the case of hard magnetic materials is high.
A large amount of coercive force is required to remove residual magnetism.

Soft magnetic material

The magnetic materials that can be easily magnetized and demagnetized are known as soft magnetic materials.
The area of the hysteresis loop of Soft magnetic material is small.
Soft magnetic materials have low hysteresis loss.
Residual magnetism can be removed with the help of a small coercive force.
