Question:

Two inductors having inductances L1 5H and L22H?

and are connected in parallel. The mutual inductance between the two inductors is M1H. Determine the equivalent inductance (in H) for this system.

Answer:

With mutual inductance the combined inductance is more complicated to calculate M1H 1/Ltotal ( L1 + L2 - 2(M)) / (L1L2 - M^2) 1/Ltotal (7-2) / (10-1) 1/Ltotal 5/9 Ltotal 1.8 H See also this page for future reference
