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.

6) A vertical pair of parallel conducting rails are separated by a width of 22 cm. They are connected at the bottom by a wire that has resistance 50 m. A uniform magnetic field of strength 2800 mT points perpendicularly to the pair of rails. A 640 gram sliding conducting bar connecting the rails is released from the top and allowed to drop under the influence of gravity. Its acceleration rapidly drops to zero, and the bar continues to fall...
