When I was first experimenting with the Hammel spinner, I tried many
different configurations, in an all out attempt to get the thing to keep
going on it's own. My brightest idea, in that area was to place the
basic device on an inverted watch crystal. I thought that the parabolic
shape would do exactly the same thing as what was mentioned in your
post. Unfortunately; what happened was that the ball bearing I was using
as the pivotal axis, would creep up the side of the glass, and either
slow down and stop; or, it would slide sideways, and the magnets would
lose their equilibrium, and jump up and stick to the ring. That happened
most, when I lubricated the crystal; in hopes, that the rotor would stop
creeping up the sides of the parabola, and just slid back down into the
'sweet zone'. I even tried pointy pivots; but, no matter what I tried,
it would find some way to counter my best efforts, to make it do what I
wanted it to.
About that experiment with the rolling aluminum cylinders. I'm sorry;
but things are not always what they seem.
Rather than the blank cylinder being "pushed" and "accelerating" the
magnet is slowing down. It just 'APPEARS', that the blank is
accelerating.
Here is why:
The cylinder with the magnets is getting hit with an EXPONENTIALLY
DIMINISHING, INCREASING, and DECREASING 'multiple whammy', of that
hysteresis stuff. First the cylinder with the magnets is inducing eddy
currents in the aluminum plate of the truck bed; and those eddy currents
are countering the forward movement of that cylinder. BUT, those same
eddy currents are (in turn) inducing their own counterparts up into the
blank, Secondly, the moving magnetic cylinder is ALSO inducing currents
directly into the blank one; AND, those eddy currents combined, are
themselves inducing a counter set of eddy currents back into the truck
bed; AND ALSO, (to some small degree) directly countering the influence
of those effects of the magnetic cylinder - (ad infinitum, world without
end, AMEN). Even in the short trip down that particular ramp, we
actually see 2 cycles of this build-up of opposing, and complimentary
forces; which causes an 'oscillation', with the result being, that both
cylinders take turns, in varying their momentum. On a much longer
aluminum ramp; I submit: that those oscillations, would eventually
widen, to the point, that the magnetic cylinder would eventually fall so
far behind, that it would be 'too far' out of the 'influence' of the
secondary eddy currents coming from the blank, and it would then
consistently 'lose momentum', in comparison to the blank, until terminal
velocity is reached, for both cylinders.
All this 'compilation of forces' adds up to produce the phenomenon
witnessed in the movie clips. It's just, that the wrong conclusion was
drawn, for the 'CAUSE', of the 'EFFECT'. It was REALLY, just that one
cylinder was going SLOWER (rather than - 'faster') than the 'norm', for
rolling cylinders, possessing equal size, and 'wind resistance'.
I would suggest, that my conclusions could be tested, by duplicating the
test setup, on both a much longer aluminum ramp; and a wooden, or
formica surface, which has no metal of any kind beneath it. Then compare
the findings. If I AM right, on the wooden ramp, the absence of the
strongest of those eddy currents (those first induced in the truck bed)
will be eliminated. and any phenomenon, will be hardly noticeable (if
noticeable at all).
But, to the experimenter, I say: "Take heart"! Any experiment (in an of
itself), is hardly ever a 'waste of time'; especially if you have
learned ANYTHING from it. You might eventually find a use, for the
principals you have observed. No experimental 'walk through the woods'
is ever "USELESS", 'in principle'; unless you give up the 'the hunt',
before you find your prey!
