Also notice upon observing the photos on Jean-Louis'
experiment page on this, and the old ATG page, the
steel rod is ejected from the small toroid side in one
case, and the large toroid side in the other case.
This sounds very much like a basic 'coil gun' effect.
The different sizes of the two toroids will probably
set up a field gradient, and cause the ejection of the
rods as opposed to the pulling in effect. It would be
harder to get a balance with the two different sizes.
I did some tests tonight, not long ago. Wound a larger
toroid, about an inch diameter, and a smaller one,
about 1/2 inch diameter. 22AWG magnet wire used,
pulsed with 50VDC from a 22,000uF capacitor (size of a
soup can..older but still got its ginger). This will
flip over small screws which are balanced on one end,
will appear to 'jerk' slighly if supported by its lead
wires. The jerking effect corresponds well to the
introduction of a nearby permanent magnet. Reverse the
magnet or the polarity to the coils, and the motion
reverses. I held this thing in my hand as well when
pulsing it, from either the 22,000uF cap or by make
and break contact with a 12V car battery. You can feel
the windings 'jumping'. Straightforward magnetic
induction effects as near as I can see.
Also, this effect works if you just use the large
toroid....it will move around metal pieces a bit on
its own. As to there being said to be no field in the
center of the toroids, this is not true. There is a
magnetic field there, the toroid itself is a 1 turn
solenoidal coil, with the windings just wrapped
'funny'. These will, upon connecting DC to them,
attempt to align themselves with the Earth's magnetic
field (or the field of a nearby permanent magnet).
As far as the laser thing goes, it could be either due
to the toroids flexing a bit, and the edges of
windings which come into the outer fringes of the beam
'lens' it, or heating of the air in the center causing
changes in its optical properties. (Ever seen 'heat
shimmer' over a hot road?) No easy way of telling
without reproducing it. Would be interesting to try
the same laser experiment with a regular solenoidal
type coil. I'm not an optics guy, so I don't have much
to add here.
One other thing, if you use two toroids which are
wound exactly the same, they will tend to attract to
one another. If you use two toroids which are wound so
as to give the same direction of B field in the
ferrite, but one is wound counterclockwise around the
periphery, and the other is wound clockwise, they will
tend to repel one another. This seems to prove the
1-turn solenoid hypothesis: in the first case, the
internal B fields are the same way, and the current is
flowing in the same directions around the periphery,
so unlike magnetic poles are set up on the sides of
the toroids which are facing each other, and they
attract...in the second case, the internal B fields
are going the same way alright, but the periphery
currents are flowing in opposite directions, thus
setting up like poles on the toroid sides facing each
other, and making them repel. Simple magnetism at its
finest.

Hehehe....yes, amazing what can be done with a few
pounds of paraffin wax, an old cardboard box, duct
tape, a heat gun and a hacksaw. And the generous help
of the college telecommunications department who
provided the microwave transmitter/receiver equipment.
Thanks for the URL, I will check it out! I was not
able to try and measure the speed of signals through
this device to any accurate degree, but it would be
interesting to try in the future. If it doesn't do
FTL, at least you can make some candles out of the
wax. ;)
