Question
The drawing shows a copper wire (negligible resistance) bent into a circular shape with a radius of 0.52 m. The radial section BC is fixed
in place, while the copper bar AC sweeps around at an angular speed of 18 rad/s. The bar makes electrical contact with the wire at all
times. The wire and the bar have negligible resistance. A uniform magnetic field exists everywhere, is perpendicular to the plane of the
circle, and has a magnitude of 4.6 x 10-3 T. Find the magnitude of the current induced in the loop ABC.
