A coaxial cable has an inner cylindrical conductor surrounded by cylindrical insulation and an outer cylindrical conducting shell. The outer shell carries the same current but in the opposite direction from that in the inner conductor as shown. If the coaxial cable sits in a uniform magnetic field directed upwards with respect to the cable, the effect of the field on the cable is

A. a net force to the left. B. a net force to the right. C. a net force upwards. D. no net force but a slight shift of the inner conductor to the left and the outer conductor to the right. E. no net force but a slight shift of the inner conductor to the right and the outer conductor to the left.
