In a model ac generator, a 498 turn rectangular coil, 10.0 cm by 29 cm, rotates at 122 rev/min in a uniform magnetic field of 0.62 T.
(a) What is the maximum emf induced in the coil?
V
(b) What is the instantaneous value of the emf in the coil at t = (/39) s? Assume that the emf is zero at t = 0.
V
(c) What is the smallest value of t for which the emf will have its maximum value?
s
