A wheel with a certain number of spokes is rotated in plane normal to earth's magnetic field so the an e.m.f. is induced between the axle and rim of the wheel. Keeping all other things same, number of spokes is changed. How is the e.m.f. affected ?

A wheel with N spokes is rotated in a plane - perpendicular to the magnetic field B such emf e is induced between axie and rim of the wheel . In the same wheel number of spokes is made 3 N and the wheel is rotated in the same manner in the same field then new emf is ________ .

A wheel with 10 spokes each of length L m is rotated with a uniform angular velocity omega in a plane normal ti the magnetic field B. The emf induced between the axle and the rim of the wheel

A wheel with 10 spokes each of length 'L' m is rotated with a unifrom angular velocity omega in a plane normal to the magnetic field 'B' . The emf induced between the axle and the rim of the wheel.

A wheel with 20 metallic spokes each 1m long is rotated with a speed of 120 rpm in a plane perpendicular to magnetic field of 0.4G. The induced emf between axle and rim of wheel will be

At which position of the rotating coil in the magnetic field, the induced e.m.f. is maximum?

A cycle wheel with 64 spokes is rotating with N rotations per second at right angles to horizontal component of magnetic field. The induced e.m.f generated between its axle and rim is E . If the number of spokes is reduced to 32 then the value of induced e.m.f. will be

A cycle wheel with 10 spoken was moved at a certain speed in a plane normal to the earth's magnetic induction. It was found that an emf of 40 mu v was induced across each spoke (i.e. Between the axis and the rim of the cycle wheel). What is the total emf induced across the ten spoken?

A wheel has three spokes and is an uniform magnetic field perpendicular to its plane, with the axis of rotation of the wheel parallel to the magnetic field. When the wheel rotates with a uniform angualr velocity omega , the emf induced between the centre and rim of the wheel is 'e' . If another wheel having same radius but with six spokes is kept in the same field and rotated with a uniform angular velocity 'omega//2' , the emf induced between the centre and the rim will be

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 ?
