Current Attempt in ProgressThe figure shows a rod of length L = 9.00 cm that is forced to move at constant speed v = 5.78 m/s along horizontal rails. The rod, rails,and connecting strip at the right form a conducting loop. The rod has resistance 0.444 02; the rest of the loop has negligible resistance.A current i= 137 A through the long straight wire at distance a = 13.4 mm from the loop sets up a (nonuniform) magnetic fieldthroughout loop. Find the (a) magnitude of the emf and (b) current induced in the loop. (c) At what rate is thermal energy generated inthe rod? (d) What is the magnitude of the force that must be applied to the rod to make it move at constant speed? (e) At what ratedoes this force do work on the rod?
