1. The problem statement, all variables and given/known data An electric generator consists of a rectangular coil of wire rotating about its longitudinal axis which is perpendicular to a magnetic field of B = 1.70 × 10-2 T. The coil measures 13.00 cm by 19.00 cm and 200.00 turns of wire. The ends of the wire are connected to an external circuit. At what speed must you rotate this coil in order to induce an alternating emf of amplitude 11.00 V between the ends of the wire? Give you answer in rev/s. Do not enter the units. 2. Relevant equations Eind=-N d(BAcos(theta))/ dt 3. The attempt at a solution I know that because this has a turning coil in a magnetic field, the above equation can become Eo=-NBA and thus Eo=0.08398 V I just don't know where to go form here or how you are supposed to find the speed?
