From: Tony on 5 Dec 2009 18:41 I've often wished that someone would make enameled soft iron "winding" wire. Then I could reverse the process - make up an arbitrarily complex winding on a simple bobbin, then wind the iron onto the copper "toroid" (all in a single pass of course). Tony

The black oxide on soft-annealed iron wire is usually sufficient insulation to suppress eddy currents.

Solder won't flow on it. https://eclient.ijsinc.com/eshop/default.aspx Jerry -- Engineering is the art of making what you want from things you can get. ����������������������������������������������������������������������� |
