In a region with a constant magnetic field as shown, there are
two conducting frictionless horizontal rails, a resistor and some
conducting wire along the left side and a conducting bar on the
right side that is free to slide left or right. The bar is
initially at rest but at time zero a force is applied to the bar
pulling it to the right so that the distance s increases with
time.
