Re: [CAD_CAM_EDM_DRO] Re: New Pix UP!

This wasn't explained to us in physics for some reason. You have two coils
opposite each other in your transformer. The field expands and collapses
over the coil opposite. The laminate stops it turning the supports into part
of the equation, fine. But if you look down on a transformer from the top it
looks like 50% of each coil is pointing the 'wrong' way. The field is
emitted in a spiral shape up each coil which should also be present _behind_
the coil pointing away from the other coil. We were told that we should
assume transformers to be close to 100% efficiency. Does the presence of
another coil somehow shape the field? This has been annoying me for a good
while, that means it's probably a really simple answer.
