Given two concentric circular loops of wire. The inner wire has a diameter of 20 cm and a clockwise current of 12 A. The outer wire has a diameter of 30 cm. What must the be the magnitude and the direction of the current in the outer wire so that the net magnetic field (Bnet) is zero at the center of the loops. Draw the current loops and show current direction.
