Question

I'm working on some homework and am stumped with this problem.  Help would be great, thanks!

A metal bar is pulled to the right perpendicular to a uniform
magnetic field. The bar rides on parallel metal rails
connected through a resistor, as shown in (Figure 1), so the
apparatus makes a complete circuit.
