Two infinite long straight parallel wire...

Two infinite long straight parallel wires A and B are separted by 0.1m distance and carry equal currents in opposite directions. A square loop of wire C of side 0.1m lies in the plane of A and B. The loop of wire C is kept parallel to both A and B at a distance of 0.1m from the nearest wire. Calculate the EMF induced in the loop C while the currents in A and B are increasing at the rate of `10^(3) A//s`. Also indicate the direction of current in the loop C.
