A wheel with 20 metallic spokes each 0.5 m long is rotated with a speed of 120 rev/min in a plane normal to the horizontal component of earth.s magnetic field `H_E` at a place. If `H_g` =0.4 G at the place, what is the induced emf between the axle and the rim of the wheel ? Note that 1G= `10^(-4)T.`
