1. A wheel with 10 metallic spokes each 0.5 m long is rotated with a speed of 120 rev/min in 83 a plane normal to the horizontal component of earth's magnetic field He at a place. If Hư = 0.4 G at the place, what is the induced emf between the axle and the rim of the wheel ? (Note that 1 G = 104 T.)
