A wheel with a certain number of spokes ...

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 ?

Text Solution

Verified by Experts

The e.m.f. induced across the spokes is in parallel. Therefore, number of spokes does not affect the net e.m.f.
