The figure below shows a rectangular, conducting loop sitting in the magnetic field of a straight wire carrying a current I. When the current I varies in time, a current is induced in the loop. Let’s assume that the current I in the straight wire decreases in time. It is observed that the induced current circulates clockwise in the loop. Use Faraday’s Law and Lenz’s Law to explain: a) Why a current is induced in the loop, b) Why the induced current circulates clockwise in the loop.
