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