    For an isotropic medium B, m, H and M are related as (where \[B,\,\,{{\mu }_{0}},\,\,H\] and M have their usual meaning in the context of magnetic material                                                      [Pb. PMT 2004]

    A)            \[(B-M)={{\mu }_{0}}H\]

    B)            \[M={{\mu }_{0}}(H+M)\]

    C)            \[H={{\mu }_{0}}(H+M)\]       

    D)            \[B={{\mu }_{o}}(H+M)\]

    Correct Answer: D

    Solution :

               Net magnetic induction \[B={{B}_{0}}+{{B}_{m}}\]\[={{\mu }_{0}}H+{{\mu }_{0}}M\]
