... A long vertical wire carries a steady 10 A current. A pair of rails are horizontal and are 0.20 m apart. A 20 ohm resistor connects points a and b, at the end of the rails. A bar is in contact with the rails, and is moved by an external force with a constant velocity of 0.40 m/s, as shown. The bar a ...
