A 0.95 m long metal bar is pulled to the right at a steady 7.1 m/s perpendicular to a uniform
Magnetic Flux: A 0.95 m long metal bar is pulled to the right at a steady 7.1 m/s perpendicular to a uniform, 2.20 T magnetic field. The bar rides on parallel metal rails connected through R= 144 Ω, as shown, so that the apparatus makes a complete circuit. You can ignore the resistance of the bar and the rails. What is the current in the wire and what direction does it flow (Clockwise or Counterclockwise)
