Determine what must be the magnitude of the current

Reference no: EM13677615

Two circular concentric loops of wire lie on a tabletop, one inside the other. The inner loop has a diameter of 20 centimeter and carries a clockwise current of 12 Amp, as viewed from above, and the outer wire has a diameter of 30 centimeter.

Determine what must be the magnitude of the current in the outer loop so that the net magnetic field due to this combination of loops is zero at the common center of the loops?
