= In the figure below, the rolling axle, 1.50 m long, is pushed along horizontal rails at a constant speed v = 11.00 m/s. A resistor R 0.4000 2 is connected to the rails at points a and b, which are directly opposite each other. The wheels make good electrical contact with the rails, so the axle, rails, and resistor form a closed-loop circuit. The only significant resistance in the circuit is R. A uniform magnetic field B = 0.0700 T is vertically downwards. 100 (a) Find the induced current I in the resistor.
