A circuit contains an emf produced by a moving metal rod of charge 13.27 μC across a magnetic field of 0.71 T, shown in the diagram. This allows a 376 Ω light bulb to turn on. If the force on the metal rod is 7 N, what would be the current running across the circuit? The length of the rod L= 2 mm. The rails and rod have a negligible electrical resistance. (Hint: This is a 3 to 4 step problem. Start by working backwards. Try using the equation for what you're solving for, and then use equations to sub in missing info)
