Explanation

(c) For paramagnetic materials, the magnetic susceptibility gives information on the molecular dipole moment and hence on the electronic structure of the molecules in the material. The paramagnetic contribution to the molar magnetic susceptibility of a material, $X$ is related to the molecular magnetic moment M by the Curie relation
$X = constant \times \frac{M}{T} \Longrightarrow X \propto \frac{1}{T}$
