Let's add a battery to the usual sliding rod set-up: B is uniform sliding rod The whole circuit is lying horizontally on the ground. The rod starts at rest, and accelerates due to the magnetic force on it. After a while, you discover that its velocity stops changing. What is the value of the final speed (in m/s) of the rod? The magnetic field is 8.27T, the battery has an emf of 6.03V, the resistor is 4.54 ohm, and the distance between the two parallel rails is 4.56m. Hint: Pay attention to the magnitude of the magnetic force on the sliding rod. Rewrite the circuit in the usual way: by replacing the sliding rod with a battery of emf=BvL; then apply Kirchhoff's loop rule.
