By definition of magnetic susceptibility. Magnetic susceptibility of diamagnetic substance is negative but with small magnitude. Variation of magnetic susceptibility of ferromagnetic substances with temperature. The slope of the given graph would give us the susceptibility. The susceptibility of diamagnetic materials does not depend upon temperature. The derivation of Langevin's susceptibility relies on the assumption that the material has a classically bound electron (rotating around an atom to create the magnetic moment), however, metals do not have localized electrons. As the temperature is raised from 0 K the interaction which leads to anti-parallel spin alignment becomes less effective until at … Therefore, A is diamagnetic and B is paramagnetic. A negative magnetization is produced when the material is exposed to external magnetic field, thus the susceptibility is negative. At all temperatures a diamagnet displays only any magnetisation induced by the applied field and a small, negative susceptibility. Susceptibility is nearly temperature independent. 2.
