Two coils connected as shown in Figure separately have inductances L1 and L2. Their mutual inductance is

Question:

Two coils connected as shown in Figure separately have inductances L1 and L2. Their mutual inductance is M.

(a) Show that this combination can be replaced by a single coil of equivalent inductance given by L e q = L1 + L2 + 2M.

(b) How could the coils in Figure be reconnected to yield an equivalent inductance of L e q = L1 + L2 + 2M. (This problem is an extension of Problem 47, but the requirement that the coils be far apart has been removed.)
