The magnetic force on the rod is measured by the balance and is found to be F. (a) What is the current in the rod in terms of the above variables? (b) Calculate the current if the force on the rod is 0.15 N, its length is 0.20 m, and the magnetic field is 0.054 T. (c) If the magnetic force on the rod is downward, in what direction is the current running in the circuit? (Clockwise or counterclockwise?)
