In the figure, a metal rod is forced to move with constant velocity along two parallel metal rails, connected with a strip of metal at one end. A magnetic field of magnitude B=0.490 T points out of the page.
(a) if the rails are separated by 35.3 cm and the speed of the rod is 45.7 cm/s, what is the magnitude of the emf generated in volts?
(b) if the rod has a resistance of 20.6 ? and the rails and connector have negligible resistance, what is the current in amperes in the rod?
(c) at what rate is energy being transferred to thermal energy?
