In a region where there is a vertical magnetic field of 1.92 10-2 T, a ring of radius 1.09 cm is flipped in the air as one would flip a coin, so that it begins rotating about a horizontal axis at the rate of 53.0 rev/s.
(a) Find the maximum instantaneous emf induced in the ring if the ring has a resistance of 9.30 10-5 ?. Find the maximum current if the ring has a resistance of 9.30 10-5 ?.
(b) What effect does the magnetic field have on the rate of rotation?
