Graphs showing the variation of magnetic properties on changing temperature: In paramagnetic material, with the increase in the magnetic field, the magnetization of the material increases. When the material is heated the magnetization starts decreasing, so the magnetization of the material is inversely proportional to temperature.

Oct 20, 2017  8. Magnetization and Saturation. When a magnetic field is applied to a ferromagnetic material, domains tend to align in the direction of the field by domain boundary movement and hence, the flux density or magnetization increases.. As the field strength increases domains which are favorably oriented to field direction grow at the expense of the unfavorably oriented ones.
