A wheel with 8 matallic spokes each 50 cm long is rotated with a speed of 120 `rev//min` in a plane normal to horizontal component of earth's magnetic field. Earth's magnetic field at the phase is 0.4 G and angle of dip `60^(@)`. Calculate the emf induced between the axle and rim of the wheel. How is the emf affected if number of spokes is increased ?

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.

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

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.

A wheel with 10 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_E 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.

A wheel with 10 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_E = 0.4 G at the place, what is the induced emf between the axle and the rim of the wheel? Note that 1 G = 10^(-4) T.
