2. You are working on a project to make a more efficient internal combustion engine. Your team is
investigating the possibility of making electrically controlled valves that open and close the input and
exhaust openings. Each valve is made of a thin, rigid rectangular piece of non-magnetic material that has
a loop of current-carrying wire along its edges. Each valve is placed in a uniform magnetic field such
that the field lies in the plane of the valve and is parallel to its short sides (of length a) as shown in the
figure below. When a switch is closed, a current I due to an external voltage source enters the short side
of the valve, splits to flow...
