In a model ac generator, a 505 turn rectangular coil 8.0 cm by 30 cm rotates at 120 rev/min in a uniform magnetic field of 0.59 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 = (π/32) 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? s
