In my calculations I was assuming no losses, too, so it doesn't
work, in
any case.

Daniel

The diagram I drew at
http://petersphotos.com/temp/transformer.jpg makes
perfect sense to me.

If you create a secondary coil in the lower half and seperate the two
circuits, it's just like a normal transformer.

If.....If.....If

What you drew *Will not* work! No if's, no but's, no maybe's!!


Ok, please redraw my diagram showing me where you think the currents
travel.


Scott, I don't have great graphics skills, but:-

If you joined the primary and secondary 0V wires, you are left with a
three contact transformer!!


In your diagram the current for the load should go the other way.
