A line charge with linear charge density λ is wound around an insulating disc of mass M and radius R of radius a pointing up. Now the magnetic field is switched off so that it is free to rotate. In the central region there is a uniform magnetic field B0 which causes the disc to rotate. Find the angular speed with which the disc starts rotating. which is then suspended horizontally as shown in Fig. 3.90
