Question

The value of mutual inductance can be increased by.

✓

Answer

$\text{M}=\mu\text{N}_1\text{N}_2\frac{\text{Area}_{12}}{\text{length}_{12}}$
$Area_{12} -$ area in common to both the coils where the flux links both of them together.
$length_{12} -$ length in common to both the coils where the flux links both of them together.
Therefore to increase the mutual inductance, the number of turns can be increased.
