A metal bar is being pulled on two metal rails with constant speed v = 0.40 m/s, as shown below. The rails are separated by a distance of 0.50 m and are located in a uniform magnetic field B = 0.060T whose direction is indicated by crosses. The rails are connected by a resistor R = 2.0 2. The resistance of rails and the bar is negligible. a. Determine the current (magnitude and direction) flowing through the resistor. A rod moving with velocity v in a uniform magnetic field.
