A pair of circular coils each having 50 turns of radius 50 cm are separated by 50 cm. A current of 10A passes through the coils which are connected in series. Midway between the coils, a coaxial flat metal disc of radius 10cm, is rotating at 1000 rpm. What is the approximate emf generated between the centre and the rim of the disc (Ho = 4x × 107 H/m) ? (A) 1.0 mv (B) 0.5 mv (C) 2.0 mv (D) 4.0 mv
