Question: Two circular wire loops are coplanar that is their areas
Two circular wire loops are coplanar (that is, their areas are in the same plane) and have a common center. The outer loop carries a current of 10 A in the clockwise direction. To create a zero magnetic field at the center of the loops, what should be the direction of the current in the inner loop? Should its current be 10 A, larger than 10 A, or smaller than 10 A?
