Distinguish between diamagnetism and  paramagnetism. Why is the magnetism paramagnetic of a substance lost on heating?

Draw a neat sketch of a cycle of magnetisation ($\mathrm{B}-\mathrm{H}$ loop/hysteresis loop) and explain the following terms :

Magnetic saturation

Residual magnetisation (retentivity)

Coercive force

Hysteresis.

Draw a neat sketch of a cycle of magnetisation ($\mathrm{B}-\mathrm{H}$ loop/hysteresis loop) and explain the term: residual magnetisation (retentivity).

Draw a neat sketch of a cycle of magnetisation ($\mathrm{B}-\mathrm{H}$loop/hysteresis loop) and explain the term coercive force.
