One of the files listed at http://keelynet.com/expcirc/expcirc.htm as
coils.zip is available to view at http://keelynet.com/gifs/coils.htm
It shows Moebius, caduceus and bifilar coils.
IMHO, in the case of bifilar, the current flowing in one direction goes
through the curve to move in opposite direction to the forward motion,
this would produce a cancellation where the current first cancels and
continues to be quenched. So if there are any effects, they would be
most pronounced at the middle of one wire, folded in half, i.e. at the
fold.
The open caduceus has been called 'anti-parallel' and notice that both
the closed and open caduceusii are at 180 degrees...so a true caduceus
would be 180 degrees. This 'anti-parallel' arrangement was used by a New
York researcher who claimed to defeat Lenz law, ridding a motor of back
emf by cancelling the magnetic component.
Others soak up the back emf into a large capacitor and phase the extra
power back into the motor. Not only does it reduce heating to make the
motor run cooler, but there is minimal field induced resistance.
The Hooper coil, according to Dr. Hoopers book located online at
http://www.geocities.com/Area51/9357/hooper01.html
shows a true moebius as in the coils.gif above. It can be polarized for
a right or left hand effect...right sucks energy AWAY from the viewer,
left sucks energy TOWARD the viewer. I've asked Patrick Flanagan if he
would give me permission to post his small booklet 'Magnetic Morphology'
as an html file with diagrams but have received no response to the
request.
A Smith coil would be 2 X 45 = 90 degrees...
Does that make sense??
