Problem
A copper rod of length 0.40m is fixed at its ends on two parallel friction-free rails so that it can slide freely. The rails are placed in a region of uniform magnetic field of magnitude 0.50T directed from south to north.
(a) The rod carries a current of 10A vertically upward. Calculate the magnitude of the magnetic force acting on the rod.
(b) State the compass direction in which the rod will begin to move.
(c) If the rod moves a distance of 8.0cm along the rails, determine the work done by the magnetic force on the rod.
