A square loop of dimension a x a is moving at a speed v toward a straight wire carrying a current I. The wire and the loop are in the same plane, and two of the sides of the loop are parallel to the wire. What is the induced emf of the loop as a function of the distance d between the wire and the nearest side of the loop? Give you answer in terms of d, the speed v, the current I, and the length of the side of the loop a.
