In a model AC generator, a 497 turn rectangular coil 6.0 cm by 30 cm rotates at 118 rev/min in a uniform magnetic field of 0.65 T. What is the maximum emf induced in the coil? V What is the instantaneous value of the emf in the coil at t = ( pi /30) s? Assume that the emf is zero at t = 0. V What is the smallest value of t for which the emf will have its maximum value? s
