Question
A long vertical wire carries a steady 8 A current. A pair of rails are horizontal and are 0.2 m apart. A 10.6 ? resistor connects points a and b, at the end of the rails. A bar is in contact with the rails, and is moved by an external force with a constant velocity of 0.5 m/s as shown. The bar and the rails have negligible resistance. At a given instant t1, the bar is 0.13 m from the wire, as shown. In Figure, at time t1, the induced current in

A long vertical wire carries a steady 15 A current. A pair of rails are horizontal and are 0.2 m apart. A 10.5 ? resistor connects points a and b, at the end of the rails. A bar is in contact with the rails, and is moved by an external force with a constant velocity of 0.5 m/s as shown. The bar and the rails have negligible resistance. At a given instant t1, the bar is 0.15 m from the wire, as shown. In Figure, at time t1, the induced current in
