The cross-sectional area of each wire is 0.007 m². The current in the larger loop goes from a counterclockwise 5.5 A to 0 A in 6.2 x 10s. Find the voltage & current in the smaller loop during the stated time interval. Assume the B-field of the larger loop is uniform (though not constant) across the smaller loop.
