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 max sin t = EE where max NBA = E is induced in the loop. The loop in this case consists of a single band ( ) 1 N = around the perimeter of a red
