Question

The coefficient of mutual inductance of two coils is $6 blank m H$ . If the current flowing in one is $2 blank a m p e r e$ , then the induced e.m.f. in the second coil will be

$3 m V$
$2 m V$
$3 V$
Zero

The correct answer is: Zero

In secondary e.m.f. induces only when current through primary changes
