Chapter 30, Problem 033 SN
The figure shows a rod of length L that is forced to move at constant speed v along horizontal
rails. The rod, rails, and connecting strip at the right form a conducting loop. The rod has
resistance R; the rest of the loop has negligible resistance. A current / through the long straight
wire at distance a from the loop sets up a (nonuniform) magnetic field throughout loop. (a)
Find the magnitude of the current induced in the loop. (b) At what rate is thermal energy
generated in the rod? (c) What is the magnitude of the force that must be applied to the rod to
make it move at constant speed? (d) At what rate does this force do work on the rod? Express
your answers in terms of the variables given and Ho.
