A small circular loop of area 2.00cm^2 is placed in the plane of, and concentric with, a large circular loop of radius 1.00m. The current in the large loop is changed at a constant rate from 200A to -200A (a change in direction) in a time of 1,00s, beginning at t=0. Because the inner loop is small, assume that the B-field is uniform over its area. What emf is induced in the smaller loop at t=0.500s?
