Two ends of an inductor of inductance L is connected to two parallel conducting rails. A conducting wire of length (that is equal to separation between the rails) can slide on the rails without friction. The wire has mass m. It is projected with a velocity v_(0) parallel to the rails (see Figure). Neglect self inductance and resistance of the loop. (a) Find velocity of the wire as a function of time. (b) Write current through the wire at time t. (c) Find speed of the wire as a function of its displacement. (d) Is the current in the conductor zero when it stops? If no, find this current . (e) Will the conductor move after it stops?
