The coil of the ac generator rotates at a frequency of f =60.0 Hz and
develops an emf of 120 V (rms). The coil has an area of A = 3.0 x 10 -3 m 2 and consists of N = 500 turns.
a. Find the magnitude of the magnetic field in which the coil rotates.
b. If the total resistance of the wire is 12Ω, what is the maximum induced current when the output terminals
are connected to a low resistance conductor?
