A rectangular coil of dimensions `40 cm xx25 cm` having 1000 turns rotates in a uniform magnetic field of strength 0.08 `Wbm^(-2)` about an axis perpendicular to the field. If the coil makes 300 revolution per minute, find the instantaneous emf when the plane of the coil make and angle of (i) `0^(@)` (ii) `45^(@)` and (iii) `90^(@)` with the magnetic lines of force.
