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

`E`

B

`2E`

C

`E//2`

D

`E//4`

Text Solution

Verified by Experts

The correct Answer is:
A
`E.M.F.` is independent of no of spokes here.
