Electromagnetic Induction

A coil has an area \(0.06 \mathrm{~m}^2\) and it has 600 turns. After placing the coil in a magnetic field of strength \(5 \times 10^{-5} \mathrm{Wbm}^{-2}\), it is rotated through \(90^{\circ}\) in 0.2 second. The magnitude of average e.m.f induced in the coil is

\(\left[\cos 0^{\circ}=\sin 90^{\circ}=1 \text { and } \sin 0^{\circ}=\cos 90^{\circ}=0\right]\)
