Question

Find the mutual inductance in the arrangement, when a small circular loop of radius $R$ is placed inside a large square loop of side $L$ ( $L \gg R$ ). The loops are coplanar and their centers coincide:

A
$M = \sqrt{2}\mu_0R^2 / L$
B
$M = 2\sqrt{2}\mu_0R / L^2$
C
$M = 2\sqrt{2}\mu_0R^2 / L$
D
$M = \sqrt{2}\mu_0R / L^2$

Accepted Answer
