A pair of parallel conducting rails that are separated by a distance d=3 m lies at a right angle to a uniform magnetic field B=0.5 T directed into the paper. A resistor R=2.5 0 is connected across the rails. A conducting bar is moving to the right at speed v = 5 m/s across the rails. What is the direction and magnitude of the current in the resistor?
