Mutual Inductance

Two coils of self-inductance 25 mH and 9 mH are placed close together such that the effective flux in one coil is completely linked with the other The mutual inductance between these coils is

Show answer and solution

Answer: (c)

Complete flux linkage: $k = 1$ , so $M = \sqrt{L_1L_2}$
$M = \sqrt{25 \times 9} = 15\text{ mH}$
So the answer is (c) 15 mH.
