The magnetic flux through a metal ring varies with time t according to
OB = 5(at3 – bt²)T · m², with a = 1.00 s-3 and b = 6.00 s-2 .
The resistance of the ring is 5.00 N. Determine the maximum current
induced in the ring during the interval from t = 0 to t = 2.00 s. Give
your answer in A.
In the figure below, the rolling axle, 2.90 m long, is pushed along horizontal rails at a constant speed v = 12.00 m/s. A resistor R = 0.4000 N is connected to the rails at points a and b, directly opposite each
other. The wheels make good electrical contact with the rails, so the axle, rails, and R form a closed-loop circuit. The only significant resistance in the circuit is R. A uniform magnetic field B = 0.0300 T is vertically
downward.
