A metal bar of length L 1.5 m slides along two horizontal metal rails as shown in Figure P21.14. A magnetic field of magnitude B 2.3 T is directed vertically.
(a) If the bar is moving at speed v 0.54 m/s, what is the emf induced across the ends of the bar?
(b) Which end of the bar is at the higher potential?
