Isn't curiosity a stinker, heheh ?
Had to get back up and read the PDF...
Anyway, here is something I did that may be helpful.
I was searching for a way to test "Wire" being sold as iron,
one of the things I (now) know is that it doesn't need to be insulated to work.
I know this one point, you don't agree with me on this point.
I took an aluminum bolt and slit the threaded end with a hacksaw,
just past the threads onto the bolt's shank a bit.
Then I chose an aluminum nut and spun it on until it stopped.
I cut off the remaining threads exposed so it was flush.
Then I wound one layer of copper wire onto the bolt's shank.
Basically an electromagnet wound on a core certain not to retain magnetism.
I would stick the test wire into the bolt's slot, and tighten the nut.
As the nut met where the threads stopped it would grasp the wire tightly.
The test wire was also wound on an aluminum bolt too,
but had a full foot long pigtail of straight wire left off it.
That pigtail would go into the first bolt's slot of course.
The stainless steel and regular steel wire would produce
very little magnetism in the test bolt core as expected.
But one of the fence wire samples I tested
produced more magnetism in the test core
than in the first copper wound test core.
Also, a meter placed across the SS and steel wire ends on the test core
produced almost no voltage due to being shorted as expected,
but that one "Iron" fence wire sample produced notable voltage,
even though by theory it should have also be shorted out too.
I kept one meter lead on the test core coil's unused end
and touched the sample coil at various points to test if
the sample might have a coating I had not detected...
I did a second test with heatshrink shrunk onto the test bolt's shank
and a piece of string wound along with the sample wire simultaniously,
to eliminate any shorting to the bolt or adjacent windings of the sample.
It produced less magnetism, but was a little shorter due to the string taking up space.
It also displayed less voltage too.
So to be fair, I unwound the string and re-wound the coil tight
with the same piece to make it short circuit again to itself only,
(I left the heatshrink on to maintain the diameter of the coil)
the magnitism increased, as did the voltage,
which being shorted now it should not have.
These are simple reproducable tests anyone can do themselves.
The other end of the test wire sample was trimmed at the bolt,
it only stuck out enough for a meter's clip lead for these tests.
I did this to prove to myself magnetic current exists,
and that it would travel into a second seperate winding,
and to test different wire samples to gauge differences.
What I did not expect was that a coil that by all accounts was shorted,
due to the wire being un-insulated and wound tightly and touching itself,
and wound onto a conductive bolt too to boot,
would produce a notable voltage across the test coil/core against logic.
I don't pretend to know why this works, or even how it does,
but it simply does, and is easy enough to reproduce yourselves.
It might be the basis for testing samples to find suitable materials to work with.
Seems to me the best core form to wind a VIC onto would be a torroid,
if the primary must be a perfect field to eliminate losses as emf I mean...
That is the only personal opinion I'll contribute at this point,
I'll just watch and read for a while now.
illuminati, I agree with all you have said, and respect your findings,
I only skimmed through the first time, and followed only a few links.
'my bad...
I'm re-reading all again,
and (also) some of the links answer a few other questions I had too.
Hope something above helps somehow.
Thanks
