CBSE · Class 12 · Physics · Magnetism and MatterThe relation between relative permeability ($\mur$) and magnetic susceptibility ($\chi$) is:
Step-by-Step Solution
The magnetic induction $B$ in a material is given by $B = \mu_0 (H + M) = \mu_0 H (1 + \chi) = \mu H$. Thus, relative permeability $\mu_r = \mu / \mu_0 = 1 + \chi$.
