Is perpendicular to a uniform magnetic field 17.0 mu T. The field magnitude drops to zero in 2.96 ms. How much thermal energy is produced in the loop by the change in field? In Fig. 30-56. 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, 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? If the rod has the resistance of 18.0 ohm and the rails and connector have negligible resistance, what is the current in the rod? At what rate is energy being transferred to thermal energy?
