Q. Mutual inductance of two coils can be increased by
A) Decreasing the number of turns in the coils
B) Increasing the number of turns in the coils
C) Winding the coils on wooden cores
D) None of the above
Explanation
(b) As $M = \frac{\mu_{0}N_{1}N_{2}A}{l},$
$\therefore\ \ M\ $ can be increased by increasing the number of turns in the coils.
