Question

A circular current loop of radius $R$ is placed inside square loop of side length $L(L ? R)$ such that they are co-planar and their centers coincide. The permeability of free space is $\mu_0$. The mutual inductance between circular loop and square loop is $\_\_\_\_$ .

Select the correct option:

A

$2 \sqrt{2} \frac{\mu_0 L^2}{R}$

B

$\sqrt{2} \frac{\mu_0 L^2}{R}$

C

$\sqrt{2} \frac{\mu_0 R^2}{L}$

D

$2 \sqrt{2} \frac{\mu_0 R^2}{L}$
