8. A long vertical wire carries a steady 10-A current. A pair of rails are horizontal and are 0.20 m apart. A 20-22 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 0.60 m/s, as shown. The bar and the rails have negligible resistance. At a given instant t,, the bar is 0.20 m from the wire, as shown. In Fig. 29.3a, at time t, what are the induced current and its direction through the resistor? Figure 29.3a 200 10 A 0.00 20 000
