Question: A conductive wire, which is shaped in a 'U' without being connected to any power supply orbattery, sits flat on a table. An external magnetic field of strength 0.75 Tesla is directed down into thetable, such that the magnetic field is perpendicular to the plane of the wire. A 32 cm long metal bar rollsalong the wire at constant velocity of 0.45 m/s toward the top of the 'U' (toward the open part of the U'not the curved part). If the wire has a resistance of 0.0125 Q, what the magnitude and direction of theinduced current in the wire?
