- The History channel had a program where they examined how those big
electromagnets were made for the scrap industry. They start with a
iron form and machine it to fit the coil. The coil starts with an
aluminum center and then they wind (flat) strip aluminum for the coil.
The insulation between windings is Nomex and they wind the aluminum
coil like a big spiral. It reminded me how capacitors were wound. Once
the coil is in the iron shell, they pot the unit with a proprietary
mix that looked like epoxy.
Winding that coil reminded me of the pancake coils that Harvey wound
before. Viewing how the company wound the aluminum coil makes me want
to go and wind some to test out some theories.
The other thing the program discussed was magnetism. Magnets always
have fields which complete the loop back into the magnet. We can see
these magnetic fields with iron filings above a sheet of paper. Now
Leedskalnin observed that the particles (he did not call them
electrons, he thought that was a bad and misleading term) formed
little tornados. These vortices would travel in a corkscrew type
motion and always in pairs. One vortex would be clockwise and the
other anticlockwise. So he saw the electron motion and the
antiparticle, the positron as the complementary pair? So when we look
at the magnetic field lines, we have to realize that a single "line"
between poles of a magnet is really a pair of vortices or counter
rotating corkscrews. If you look at the picture at here
you can almost make out pairs of lines.
Someone told me Leedskalnin used pairs of coils but one coil was iron
and that was the secret of his device. Soft iron, which when used for
electric wire, is internally equivalent to a bifilar pair of copper &
aluminum wires, because iron has two open valence bands in its atomic
arrangement. Roy Meyers also devised a free energy device that used
iron wire. (http://www.rexresearch.com/meyers/meyers.htm). Sounds
similar to Leedskalnin and around the same time (a little earlier than
Hope this helps!
