A) \[(B-M)={{\mu }_{0}}H\]
B) \[M={{\mu }_{0}}(H+M)\]
C) \[H={{\mu }_{0}}(H+M)\]
D) \[B={{\mu }_{0}}(H+M)\]
Correct Answer: D
Solution :
When a magnetic material is placed in a magnetic field, the magnetic material gets more magnetised. Hence, the net magnetic field is given by, \[B={{B}_{0}}+{{B}_{m}}={{\mu }_{0}}H+{{\mu }_{0}}M\] \[={{\mu }_{0}}(H+M)\]
