Hi,
I want to know what the different methods out there to make a rotating field electrically. I am perticularly interested in the types that are produced by toroidally wound coils like the one here: http://upload.wikimedia.org/wikipedia/en/7/7a/RMFpatent.PNG but I want to know if it is better to use a ferrous or air core to produce the field on? I've also heard about Helmholtz coils being used to create the field. Which do you think would be best?
Thanks,
Jason O
