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 = 0.517 T points out of the page.
(a) If the rails are separated by 26.9 cm and the speed of the rod is 60.7 cm/s, what is the magnitude of the emf generated in volts?
(b) If the rod has a resistance of 22.8 ? 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?
