Two parallel conducting wires are connected by a light bulb (represented by a resistor). A non ferrous bar is placed across the two wires. The entire setup is placed in a uniform magnetic field. On paper, the wires are drawn horizontally and the magnetic field is out of the page. Initially bar is pulled to the right at a constant speed. Which direction is the current through the circuit formed by the resistor, wires, and bar?a. There no current. b. clockwise c. Counter clockwise.
