we know,

susceptibility = intensity of magnetization (I) / Magnetizing intensity (H)

permeability = 1 + susceptibility

for a perfectly diamagnetic substance,

intensity of magnetization (I) = - Magnetizing intensity (H)

negative sign shows that the opposite alignment of electrons against the direction of applied magnetic field.

thus, susceptibility = -1 ( acts as super conductor )

and, permeability =0 ( no magnetic lines of force pass through the material )

Permeability can also be understood by opposite nature because the magnetic field produced will be in opposite direction to the applied field which will create repulsion and no lines will pass through.

Define magnetic hysteresis and write it's significance.

Lagging of magnetic field behind the magnetizing field in a ferromagnetic material taken through a cycle of magnetization is called the hysteresis.

From the hysteresis loop, a number of primary magnetic properties of a material can be determined.

Retentively- A measure of the residual flux density corresponding to the saturation induction of a magnetic material. In other words, it is a material's ability to retain a certain amount of residual magnetic field when the magnetizing force is removed...
