In a model AC generator, a 497 turn rectangular coil 7.0 cm by 26 cm rotates at 123 rev/min in a uniform magnetic field of 0.61 T.
(a) What is the maximum emf induced in the coil?
(b) What is the instantaneous value of the emf in the coil at t = (?/36) s? Assume that the emf is zero at t = 0.
(c) What is the smallest value of t for which the emf will have its maximum value?
