Movement within this field is described by direction and is either axial or diametric. Magnetization is caused by a magnetic moment this is brought about by the portability of electrons in atoms. The reaction of a substance to an outer magnetic field decides its net magnetization. The ratio of the strength of magnetizing field to the permeability of free space is called as magnetic intensity. The strength of magnetic field at a point can be given in terms of vector quantity called as magnetic intensity (h). The si unit of magnetic intensity is am 1.
