A wheel with 8 metallic spokes each 50 cm long is rotated with a speed of 120 rev. "min"^(-1) in a plane normal to the horizontal component of the Earth's magnetic field. The Earth's magnetic field at the place in 0.4 G and the angle of dip is 60^(@) . Calculate the emf induced between the axle and the rim of the wheel. How will the value of emf be affected if the number of spokes were increased.
