A small square loop of wire of side l is placed inside a large square loop of wire of side L (L gt gt l ) . The loops are coplanar and their centres coincide. Find the mutual inductance of the system.

A small square loop of wire of side l is placed inside a large square loop of wire of side L(Lgtgtl) . The loops are co-planer and their centres coincide. The mutual inductance of the system is proportional to
