Among the following, for which substance does the magnetic susceptibility not depend on the temperature?

$A$ thin,lightweight rod of a diamagnetic substance,such as silver,is suspended in a uniform external magnetic field. It will align itself with its length:

For two types of magnetic materials $A$ and $B$, the variation of $\frac{1}{\chi}$ ($\chi$: magnetic susceptibility) versus temperature $T$ is shown in the figure. Then:

If $\chi$ is the magnetic susceptibility and $\mu_{r}$ is the relative permeability of a ferromagnetic substance, then:

Which of the following statements is correct for diamagnetic materials?

There are $2.0 \times 10^{24}$ molecular dipoles in a paramagnetic salt. Each has a dipole moment of $1.5 \times 10^{-23} \text{ A m}^2$. Find the maximum (saturation) magnetization in the specimen. (in $\text{ A m}^2$)
