Physics - EMI/AC Question with Solution | TestHub

A square shaped coil of area $70{\mathrm{cm}}^2$ having 600 turns rotates in a magnetic field of $0.4{\mathrm{wbm}}^{-2}$, about an axis which is parallel to one of the side of the coil and perpendicular to the direction of field. If the coil completes 500 revolution in a minute, the instantaneous emf when the plane of the coil is inclined at $60^{\circ }$ with the field, will be $\_\_\_\_$ V. (Take $\pi =\frac{22}{7}$ )
