Question

For an isotropic medium, $B,\, \mu,\, H$ and $M$ are related as (where $B, \mu_{0}, H$ and $M$ have their usual meaning 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. $B=\mu_{0}(H+M)$

Answer 1

Answer: (D)

Net magnetic induction $B=B_{0}+B_{m}=\mu_{0} H+\mu_{0} M$
