Electromagnetic Induction

Two coils \(\mathrm{A}\) and \(\mathrm{B}\) have mutual inductance 0.008 \(\mathrm{H}\). The current changes in the coil A, according to the equation \(\mathrm{I}=\mathrm{I}_{\mathrm{m}} \sin \omega \mathrm{t}\), where \(\mathrm{I}_{\mathrm{m}}=5 \mathrm{~A}\) and \(\omega=200 \pi ~\mathrm{rad} ~\mathrm{s}^{-1}\). The maximum value of the e.m.f. induced in the coil \(B\) in volt is
