Q. For an isotropic medium $B,\ \mu,\ H$ and $M$ are related as (where $B,\ \mu_{0},\ H$ and $M$ have their usual meanings in the context of magnetic material)
A) $(B - M) = \mu_{0}H$
B) $M = \mu_{0}(H + M)$
C) $H = \mu_{0}(H + M)$
D) $B = \mu_{0}(H + M)$
Explanation
(d) Net magnetic induction $B = B_{0} + B_{m} = \mu_{0}H + \mu_{0}M$
