Intensity of magnetisation (I). When a magnetic material is subjected to a magnetising force, the material is magnetised. Intensity of magnetisation is a measure of the extent to which the material is magnetised and depends upon the nature of the material. It is defined as under The intensity of magnetisation of a magnetic material is defined as the magnetic moment developed per unit volume of the material. Intensity of magnetisation, I = M / V where M = magnetic moment developed in the material V = volume of the material If m is the pole strength developed, a is the area of Xsection of the material and 2l is the magnetic length, then,
Hence intensity of magnetisation of a material may be defined as the pole strength developed per unit area of crosssection of the material.
SI units of I are A m^{1}

Intensity of magnetisation (I). It is defined as the pole strength per unit area of the bar or magnetic moment per unit volume of the bar. It is denoted by letter I.
