Induction and energy transfer
A metal rod is forced to move constant velocity V along two parallel metal rails, connected with a strip of metal at one end. A magnetic field of magnitude B = .350T points out of the page.
a) if the rails are separated by a 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 18ohms and the rails and connector have negligible resistance, what is the current in the rod?
c) at what rate is energy being transfered to thermal energy?
