Question

(hrwc31p12) A small circular loop of area 3.0 cm is placed in the plane of, and concentric with, a large circular loop of ra- dius 1.0 m. The current in the large loop is changed uniformly from 200.0 A, counterclockwise, to -200.0 A, clockwise, in a time of 1.0 s, beginning at t 0.0 s. 25 pt What emf is induced in the small loop at t 0.5 s? Take emf as positive if counterclockwise. Note that since the inner loop is small, you can assume that the B field due to the outer loop is uniform over the area of the smaller loop. lin V) 2.
