The following figure shows a copper wire bent into a circular shape with a radius of 0.50 m. B (into paper) x x B ww 3.0 Ω x Wire x x x x x The radial section BC is fixed in place, while a copper bar AC sweeps around at an angular speed of 15 rad/s. The bar makes electrical contact with the wire at all times. Both the wire and the bar have negligible resistance. The uniform magnetic field is perpendicular to the plane of the circle, and has a magnitude of 3.8 × 10-3 T. Find the magnitude of the current induced in the loop ABC.
