Question:

Two coils of self inductances $L_1$ and $L_2$ are kept close to each other so that the effective flux in one is completely linked with the other. What is the mutual inductance M between them?

Options:

$L_1 L_2$

${L_1 L_2}^{-1}$

$(L_1 L_2)^2$

$(L_1 L_2)^{1/2}$

Correct Answer:

$(L_1 L_2)^{1/2}$

Explanation:

The correct answer is Option (4) → $(L_1 L_2)^{1/2}$
