Experiments on the Induced e.m.f. in a circuit by a Changing Magnetic Flux problem 9


A coil with 18 turns and cross-sectional area of is laid along the north pole of a magnet, and then it is turned the opposite way in time 17 ms. The magnetic field density at the north pole of the magnet is 0.3 T. What voltage is induced?
