Liquid oxygen remains suspended between two pole faces of a magnet because it is

Explain quantitatively the order of magnitude difference between the diamagnetic susceptibility of ${N_2} \left( { \sim 5 \times {{10}^{ - 9}}} \right)$ (at $STP$) and ${Cu} \left( { \sim {{10}^{ - 5}}} \right)$.

Which of the following curves represents the variation of magnetic moment $(M)$ with temperature $(T)$ for a ferromagnetic material?

The product of magnetic susceptibility $(\chi)$ and absolute temperature $(T)$ is constant for a

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

Why is the magnetic susceptibility of diamagnetic materials negative? Explain.
