The figure shows a conducting rod sliding over two bare wires. The wires are in a horizontal plane (ignore gravity) and are connected through the resistor R. A uniform magnetic field points out of the page everywhere. Friction between the rod and the wires is negligible. At the instant shown, the rod is moving from right to left, toward R, with a speed v. (A hand got the rod startedbefore the instant shown, but is no longer in contact with it.) Which one of the following is true at the instant shown?Image2.gif Current is flowing through R from a to b. Current is flowing through R from b to a There is no current flowing through R. An alternating current is flowing. The rod experiences no net force.
