Suppose that a coil consisting of 75 turns of wire shaped as a circular loop with a radius of 12 centimeters is placed with its face perpendicular to the direction of a sinusoidally alternating magnetic field whose frequency is 60 Hz and whose maximum magnitude B0 = 0.13 Tesla. Will the coil be able (in principle) to illuminate a nornal 120 volt light bulb? (Note: the emf of 120 volt household alternating current actually oscillates between +/- 170 volts. Technically, 120 volts is the square root of the average squared emf, the square ensuring that what you are averaging is positive.) (Hint: the answer is yes)
