Q 8. In the figure above, two concentric rings have current running through them in the directions shown. Assuming that both currents can be adjusted to any magnitude other than o (but always in the directions shown), where is it possible for the net magnetic field to be o ? I. Inside the inner ring II. Between the two rings III. Outside the outer ring (A) I only (B) I and III only (C) II only (D) II and III only (E) None of the above
