You need to make a generator for your bicycle light that will provide an alternating emf whose peak value is 4.2 V. The generator coil has 55 turns and rotates in a 0.040-Tesla magnitude magnetic field. If the coil rotates at 400 revolutions per second, what must the area of the coil be to develop this emf?
