A1.41-m bar moves through a uniform, 1.20-T magnetic field with a speed of 2.50 m/s (Fig. 29.40). In each case, find the emf induced between the ends of this bar and identify which, if any, end (a or b) is at the higher potential. The bar moves in the direction of(a) The + x-axis;(b) The ?? y-axis;(c) The + z-axis.(d) How should this bar move so that the emf across its ends has the greatest possible value with b at a higher potential than a, and what is this maximumemf?
