A cycle wheel contains 24 spokes each of 0.5 m length. It is rotated in a horizontal plane with 120 revolution/min. In the effect of the earth's magnetic field. If the total magnetic field of the earth is 104 G, then dynamic emf across the centre and the rim of the wheel (angle of dip is 30∘) will be:-
