A bicycle wheel of radius 0.5 m has 32 spokes. It is rotating at the rate of 120 revolutions per minute, perpendicular to the horizontal component of earth's magnetic field `B_(H) = 4 xx 10^(–5)` tesla. The emf induced between the rim and the centre of the wheel will be-

A wheel with 20 metallic spokes each of length 8.0 m long is rotated with a speed of 120 revolution per minute in a plane normal to the horizontal component of earth magnetic field H at a place. If H=0.4xx10^(-4) T at the place, then induced emf between the axle the rim of the wheel is

A gramophone disc of brass of diameter 30 cm rotates horizontally at the rate of 100//3 revolutions per minute. If the vertical component of the earth's magnetic field be 0.01" weber"//"metre"^(2) , then the emf induced between the centre and the rim of the disc will be-

A wheel with 10 metallic spokes each 0.5m long is rotated with a speed of 120 revolutions/min in a plane normal to the horizontal component of the 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 axxk and the rim of the wheel ? Take, 1 gauss (G)=10^(-4)T.

A wheel with 10 metallic spokes each 0.5m long is rotated with a speed of 120 rev/min in a plane normal ot the horizontal components of earth's magnetic field B_(H) at a place. If B_(H)= 0.4G 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 0.5m 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)=0.4G at the place, what is the induced emf between the axle and the rim of the wheel? Note that 1G=10^(-4)T .

For a place the Earth's magnetic field is 4 xx 10^(-5) T and angle of dip is 60^(@) . A wheel of radius 60 cm having 10 spokes is rotating with a speed of 150 "rev" // "min" in plane perpendicular to Earth's horizontal magnetic field. Find the induced emf between axle and rim of the wheel.
