Stupid question about yokes…

[CarrieGordon]

The book talks about the importance of having a yoke on a machine that is not iron or steel. Does the yoke have to be made out of iron or steel? And is the sole reason for it magnetism?

I do beleive that they are either iron or steel, and yes it is for the magnatism.

YES – you need a ferrous metal yolk to complete the horse shoe effect of the coils.
It will work w/o it – but better results if you have the yolk (on non-ferrous metal frame machines)

Good question – sorry for not making that clear in the book!

Ok, thanks! Really, someone else probably could have been assumed it needed to be a metal capable of being magnatized since it the book WAS talking about magnetism, however, I didn’t want to make that assumption on my own and be wrong.
