The relative permeability of iron is $5500$. What will be its magnetic susceptibility?

Curie's law states that

The magnetic susceptibility of the material of a rod is $499$. Permeability of vacuum is $4 \pi \times 10^{-7} \ H/m$. The absolute permeability of the material of the rod in $H/m$ is:

What does the magnetic susceptibility of a material show?

$A$ rod of ferromagnetic material with dimensions $10 \, cm \times 0.5 \, cm \times 0.2 \, cm$ is placed in a magnetic field of strength $0.5 \times 10^4 \, Am^{-1}$. As a result,a magnetic moment of $5 \, Am^2$ is produced in the rod. The value of magnetic induction will be.... $T$

An iron bar having a cross-sectional area of $2 \times 10^{-5} \ m^2$ and a magnetising field of $2400 \ A/m$ produces a magnetic flux of $2.4 \pi \times 10^{-5} \ Wb$. What will be the value of permeability $(\mu)$ and susceptibility $(\chi)$ of the bar? (Given $\mu_0 = 4 \pi \times 10^{-7} \ T \cdot m/A$)
