The relationship between the magnetic susceptibility ( $\chi$ ) and the magnetic permeability $(\mu)

Question

The relationship between the magnetic susceptibility ( $\chi$ ) and the magnetic permeability $(\mu)$ is given by :\ $\left(\mu_{0}ight)$ is the permeability of free space and $\mu_{r}$ is relative permeability)\

(d) : $\mu_{r}=\left(1+\chi_{m}ight)$\ $\chi_{m}=\mu_{r}-1$\ $\chi_{m}=\left(\frac{\mu}{\mu_{0}}-1ight)$\ As $\mu_{r}=\frac{\mu}{\mu_{0}}$\
