Electromagnets to stir water

You want to use electromagnet(s) to move something -through- a stainless steel vessel?

What's the problem?

Stainless steel is a conductor. The moving field will make lots of eddy current in the conductor and that is where the power will go. Better to use a glass vessel.

So even though SS is not magnetic it won't pass a smooth EM field to the inside of the vessel? If this won't work then my whole idea is shot. I have to use a SS vessel that I can tig weld for the heat exchanger coil and hot water element.
