Two lined conductors are connected by a resistor R=30Ω, and separated by L=5. A moving conductor of mass m slides on the conductors at a constant speed v, which produces a current I=4 A. The conductors are placed in a B=6T magnetic field out of the page. In what direction does the current flow through the moving conductor when the bar is sliding in the direction as shown in the figure? From the previous question, calculate the speed at which the bar is moving. From the previous question, calculate the magnitude and direction of magnetic force on the bar.
