Two circular coils are concentric and lie in the same plane. The inner coil contains 160 turns of wire, has a radius of 0.015 m, and carries a current of 6.9 A. The outer coil contains 220 turns and has a radius of 0.022 m. What must be the magnitude of the current in the outer coil, such that the net magnetic field at the common center of the two coils is zero?
