Vedclass · Answer

(D) The permeability $\mu$ is related to magnetic field $B$,magnetic field intensity $H$,and magnetic flux $\Phi$. From the relation $B = \mu H$,the unit of $\mu$ is $	ext{Tesla} / (	ext{Ampere/metre}) = 	ext{Tesla metre per ampere}$ $(T \cdot m \cdot A^{-1})$. Since $1 	ext{ Tesla} = 1 	ext{ Weber/metre}^2$,the unit becomes $(	ext{Weber/metre}^2) \cdot 	ext{metre} / 	ext{Ampere} = 	ext{Weber per ampere metre}$ $(Wb \cdot A^{-1} \cdot m^{-1})$. Also,the inductance $L$ of a solenoid is given by $L = \mu n^2 A l$,where $\mu$ has units of $	ext{Henry/metre}$ $(H \cdot m^{-1})$. Therefore,all the given units are equivalent and correct.
