A coil is made up of 19 square loops with the sides equal to 5.3 cm. The coil is placed in a uniform 350 mT magnetic field with the axis of the coil parallel to the magnetic field. If the field reverses direction in 0.17 seconds, what is in volts, the average emf induced in the coil?

Answer 1

V = N*A*dB/dt
= (# of loops)*(Area)*(0.35 T)/(0.17 s)

Answer 2

.688
