Answer (Detailed Solution Below)
Detailed Solution
Download Solution PDFHard magnetic material
- 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.
