Vedclass · Answer

(D) The relative permeability $\mu_r$ of a magnetic material is defined as the ratio of the permeability of the material $\mu$ to the permeability of free space $\mu_0$,given by $\mu_r = \frac{\mu}{\mu_0}$.Also,the relationship between relative permeability and magnetic susceptibility $\chi_m$ is given by $\mu_r = 1 + \chi_m$.Equating these two expressions,we get $\frac{\mu}{\mu_0} = 1 + \chi_m$.Therefore,the permeability of the material is $\mu = \mu_0(1 + \chi_m)$.

If $\mu_0$ is the permeability of vacuum and $\chi_m$ is the magnetic susceptibility,then the permeability of the material $\mu$ is . . . . . . .
