$\mu_{0}$ is permeability of vacuum, $\chi_{m}$ is susceptibility then permeability of material is
1 $\mu=\mu_{0} 1+\chi_{\mathrm{m}}$
2 $\mu=\mu_{0}\left(\chi_{\mathrm{m}}-1\right)$
3 $\mu=\mu_{0}\left(1-\chi_{m}\right)$
4 $\mu=\mu_{0}\left(1+\chi_{m}\right)$
Explanation:
D The relation between the permeability of the vacuum and the magnetic susceptibility is $\mu=\mu_{0}\left(1+\chi_{m}\right)$
