Note the similarity between the situation in this problem and a generator. In a generator,
one normally has a loop rotating in a constant magnetic field so the flux through the
loop varies sinusoidally in time. In this problem, we have a stationary loop in an
oscillating magnetic field, and the flux through the loop varies sinusoidally in time. In
both cases, a sinusoidal emf
