A Square Loop Of Wire Of Side A Lies Midway

A square loop of wire, of side a, lies midway between two long wires, 3a apart. and in the same plane. (Actually, the long wires are sides of a large rectangular loop, but the short ends are so far away that they can be neglected.) A clockwise current I in the square loop is gradually increasing: dl/dt = k (a constant). Find the emf induced in the big loop. Which way will the induced current flow?
