Vedclass · Answer

(D) The relationship between relative permeability $\mu_r$ and magnetic susceptibility $\chi$ is given by the formula: $\mu_r = 1 + \chi$.For ferromagnetic substances,the magnetic susceptibility $\chi$ is a large positive value,typically $\chi >> 1$.Consequently,the relative permeability $\mu_r$ is also much greater than $1$ (i.e.,$\mu_r >> 1$).Therefore,the correct condition for a ferromagnetic substance is $\chi >> 1$.

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