In Figure , a metal rod is forced to move with constant velocity v along two parallel metal rails, connected with a strip of metal at one end. A magnetic field of magnitude B = 0.350 T points out of the page.
(a) If the rails are separated by L = 25.0 cm and the speed of the rod is 55.0 cm/s, what emf is generated?
(b) If the rod has a resistance of 18.0Ω and the rails and connector have negligible resistance, what is the current in the rod?
(c) At what rate is energy being transferred to thermal energy?
