Q. The long straight wire carries a constant current I with the direction upward. A square conductor with side s is moving with constant speed v, and the distance between the wire and one of the side of the conductor is r. Calculate the induced emf in the conductor and if the total resistance in the conductor is R what is the magnitude of the induced current?

Q. A wheel is spinning clockwise at a 10.0 revolutions per second at t = 0. Due to friction in the bearings supporting the axle, the wheel slows down, losing 0.500 revolutions per second in angular velocity each second, until it comes to rest. How many complete revolutions does the wheel turn before coming to rest?
