The drawing shows a copper wire (negligible resistance) bent into a circular shape with a radius of 0.54 m. The radial section BC is fixed in place, while the copper bar AC sweeps around at an angular speed of 19 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 4.1 x 10-³ T. Find the magnitude of the current induced in the loop ABC.
