Magnetisation: B, H, M, χ & μ question from MHT CET 2025 (19 Apr, Shift 2)

Q15MHT CET 2025 · 19 APR · SHIFT 2Easy

Magnetisation: B, H, M, χ & μ

If $M$ is the magnetisation induced in the material, H is the magnetic field intensity, B is the net magnetic field inside the material then the correct relation between them is ( $\mu_0 =$ permeability of free space)

Show answer and solution

Answer: (d)

Inside a material the field has two parts: the applied $\mu_0 H$ and the extra $\mu_0 M$ from magnetisation.
$B = \mu_0(H + M)$
So the answer is (d).
