A circular coil of area 100 cm2 & 20 turns is kept in magnetic field of flux density 2 Wb−m2. It rotates from a position where its plane makes an angle of 30° with the field to a position perpendicular to the field in a time 0.2 sec. Find the magnitude of the emf induced in the coil due to its rotation.
