$A$ sensitive magnetic instrument can be shielded very effectively from outside magnetic fields by placing it inside a box of

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 $\text{ A m}^2$)

Given below are two statements:
Statement $I$: The diamagnetic property depends on temperature.
Statement $II$: The induced magnetic dipole moment in a diamagnetic sample is always opposite to the magnetizing field.
In the light of the given statements,choose the correct answer from the options given below:

$A$ paramagnetic material has $10^{28} \text{ atoms/m}^3$. Its magnetic susceptibility at temperature $350 \text{ K}$ is $2.8 \times 10^{-4}$. Its susceptibility at $300 \text{ K}$ is
