The relation between the magnetic susceptibility $\chi$ and the relative magnetic permeability $\mu_r$ is:

Curie's law states that

$A$ magnetic intensity of $500 \,A/m$ produces a magnetic flux of $2.4 \times 10^{-5} \,Wb$ in an iron bar of cross-sectional area $0.4 \,cm^2$. The magnetic permeability of the iron bar is

$A$ bar magnet has length $4 \text{ cm}$,cross-sectional area $2 \text{ cm}^2$ and magnetic moment $6 \text{ Am}^2$. The intensity of magnetisation of the bar magnet is

If the relative permeability of iron is $5500$, then its magnetic susceptibility is:

$A$ substance has a mass of $1 \, g$ and a density of $5 \, g/cm^3$. Its magnetic dipole moment is $6 \times 10^{-7} \, A \cdot m^2$. What is the magnetization in $A/m$?
