Electromagnetic Induction

Question:

A Circuit contains two inductors of self inductance L1 and L2 in series. If M is the mutual inductance, then the effective inductance of the circuit will be 

Options:

L1+L2     

 L1+L-2M

L1+L+M

L1+L+2M

Correct Answer:

L1+L+2M

Explanation:

when inductances are connected like this in series, then

                        L = L1+L2+2M
