Work Step by Step
More random thermal motion takes place at higher temperatures, which inhibits the alignment of the atoms’ magnetic moments. If the moments don’t align as well with an external applied field, this reduces the magnetization of the paramagnetic material, and the permeability, and the susceptibility. A diamagnetic material has no net magnetic moment and its diamagnetic properties do not rely on the orientation of any permanent atomic dipoles. The negative magnetic susceptibility is largely unaffected by temperature.
