A line charge lambdaper unit length is lodged uniformly onto the rim of a wheel of mass M and radius R. The wheel has light non-conducting spokes and is free to rotate without friction about its axis (Fig.) . A uniform magnetic field extends over a circular region within the rim. It is given by, {:(B=-B_0 K,(r le a , a lt R)),(=0,"(otherwise)"):} |
