Vedclass · Answer

(C) The magnetic permeability $\mu$ is defined by the relation $B = \mu H$, where $B$ is the magnetic flux density and $H$ is the magnetic field intensity.Since the unit of $B$ is Tesla $(T)$ or $Weber/m^2$ $(Wb/m^2)$ and the unit of $H$ is $Ampere/meter$ $(A/m)$,the unit of $\mu$ is $(Wb/m^2) / (A/m) = Wb / (A m)$.Since $1 \ Henry (H) = 1 \ Wb/A$, the unit of $\mu$ can be written as $H/m$ or $Henry m^{-1}$.Therefore, the correct option is $C$.

The $S.I.$ unit of magnetic permeability is
