The rails have negligible resistance but the rod has resistance R. Initially the rod is at rest, but at time t = 0 the switch is closed connecting the rod to a battery of Ɛ volts. Find the velocity of the rod as a function of time.

Two parallel rods are each 0.62 m in length. They are attached at their centers to a spring that is initially neither stretched nor compressed. The spring has a spring constant of 220 N/m. When 1300 A of current is in each rod in the same direction, the spring is observed to be compressed by 2.0 cm.

A flexible copper cable forms a conducting loop in the presence of a magnetic field of strength 5.0 x 10-3 T into the page, as shown at left. The ends of the wire pass through a narrow rubber ring and are finally attached to a 10-0 resistor . The resistor is then pulled downward, pulling the wire through the ring and reducing the size of the loop. Assume that the resistor is carefully pulled at a speed so that the area of the loop diminishes at a rate of 0.10 m2/s. a) What emf is induced in the wire?b) In which direction, clockwise or counterclockwise, will the induced current start to flows in the wire loop? c) Assuming the resistance of the copper cable is negligible, what is the current through the resistor?
