The drawing shows a copper wire (negligible resistance) bent into a circular shape with a radius of 0.44 m. The radial section BC is xed in place, while the copper bar AC sweeps around at an angular speed of 15 rad/s. The bar makes electrical contact with the wire at all times. The wire and the bar have negligible resistance. A uniform magnetic eld exists everywhere, is perpendicular to the plane of the circle, and has a magnitude of 4.9 x 10'3 T. Find the magnitude of the current induced in the loop ABC. Ti (into paper) Number l Units v
