Point b is at higher potential. FIG. P31.57 (d) No . Magnetic flux will increase through a loop to the left of ab . Here counterclockwise current will flow to produce upward magnetic field. The current in R is still from b to a . P31.58 = A at a distance r from wire µ π = F H G I K J 0 2 I r v A v FIG.
