Intensity of magnetisation of a magnetic material is defined as ……………..per unit……………..of the material.

Define intensity of magnetisation.

The intensity of magnetisation of a magnetic material is l . Now material is the cut such that volume of the material is halved, then new intensity of magnetization is

Write the units of magnetisation and magnetic intensity.

Magnetic moment per unit volume of the material is called ……………. of the material.

Discuss magnetisation of a ferromagnetic material with help of Rowland ring .
