Main Question or Discussion Point

If iam using a magnetic material as a shaft. The rotating shaft in a magnetic field can cause the flow of current? resulting current flow in shaft?? please clarify me...

The shaft doesn't need to be of a magnetic material, any material that conducts electricity will do. Unless your shaft is an odd shape, there should not be much to worry about. A long thin solid metal cylindrical shape spinning on its longitudinal axis won't have much circulating current. If the shaft were made of layers and strips of a conductor separated by an insulating material in a really strong field this might cause problem voltages and currents.

Do you have an unusual application in mind?

Thanks for your valuable reply. whatever you said is good but really i have a different thought please clear me what the major differences when i use the shaft materials as iron & Stainless steel.

They would have quite different mechanical capabilities, but I can't imagine the electrical differences (if any) would be significant in this respect.

can i define iron as a magnetic material & ss as a non magnetic material ??? If so What about the leakage currents condition in shaft Materials of both magnetic & non magnetic materials???

Please answer with patience dont think as foolish bcoz i m poor in this......

Do you have a magnet you can test to see whether it attracts one of your kitchen SS knives?

A shaft could be made of a non-magnetic material such as brass, or fibreglass.

It seems that I'm not going to have my question answered?
