A closed coil having 100 turns is rotated in a uniform magnetic field \( B=4 \cdot 0 \times 10^{-4} \mathrm{~T} \) about a diameter which is perpendicular to the field. The angular velocity of rotation is 300 revolutions per minute. The area of the coil is \( 25 \mathrm{~cm}^{2} \) and its resistance is \( 4.0 \Omega \). Find (a) the average emf developed in half a turn from a position where the coil is perpendicular to the magnetic field, (b) the average emf in a full turn and (c) the net charge displaced in part (a).
