15 The drawing shows a copper wire of negligible resistance bent into a circular shape with a radius of r The radial section BC is fixed in plane while the copper bar AC sweeps around at an angular speed of w 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 B Which of the following shows the magnitude of the current as a function of 0 A I C 2 0 COLO B D T B 1 wn 302 B into paper wire NBAW Lino T sin st 0 6 df t case 2
