Question

A coil of $N$ turns and mean cross-sectional area $A$ is rotating with uniform angular velocity $omega$ about an axis at right angle to uniform magnetic field $B$ . The induced e.m.f. $E$ in the coil will be

$N B A \sin ω t$
$N B ω \sin ω t$
$N B / A s i n ω t$
$N B A ω \sin ω t$

The correct answer is: $N B A blank omega sin invisible function application omega t$
