Part 1: A 500g bar 0.8m across moves with a velocity +5.0 meters per second. The total resistance of the wire is 0.5 ohms. The magnitude of the B-field is 1200mT into the page. What is the change in the flux with respect to time? What is the induced electromotive force? What is the induced current in the wire? What is the direction of the current? What is the magnitude and direction of the force on the bar caused by this current?

Part 2: A 1500g bar 0.25m across moves with a velocity -0.4 meters per second. The external force on the bar is 100N to the left so maintain the velocity. The total resistance of the wire is 50 ohms. What is the magnitude and direction of the change in the external B-field? What is the current's magnitude and direction of the external B-field? What is the current's magnitude and direction flowing through the wire?
