Hamdi responds:

To Vortex:

It is easy to rule out induction:

1. Simulations gave experiments results. Fig. 6.2 and 6.3.

2. The key effect of the levitation is the repulsion and it is inversely
proportional to the square of rotating field frequency as shown Fig. 5.25.
Anyone can measure this repulsion by putting a magnet of any kind and any
shape and in any orientation on a soft spongy block on a balance and
approach another rotating magnet where it's poles are well aligned, lying
on the rotation plane. That is orthogonal to the rotation axis. Since
magnets have some factory misalignment, there is a need for a control
experiment. This is gluing the test magnet to a marble block at least half
kg through one of its pole and put this block again on the balance again
over a cushion. This marble block would suppress vibration of the test
magnet when subjected to the rotating field. If the rotating magnet is well
aligned, balance will register zero or few tens mg force. supposing the
rotating magnet has a speed above 6000 RPM and the gap between magnets is
about 10 - 20 mm. If the balance reading does not even get decrease by
increasing the speed, for example at 12000 RPM, one can conclude that the
rotating magnet alignment is not good. Finally having good alignment, real
test can be started. One can immediately will see the balance will start to
register loads starting from grams up to 100 grams at 3000 to 6000 RPM. By
increasing the speed the load will be decreased as I specified by the above
relation. From this test one can see the registered force is dependent to
the vibration of the test magnet in contrast to the force caused by
induction is not.

3. Section 5.2 is dedicated to calculation of this force based of angular
vibration of the test magnet by exclusion of its translational vibration.
That one is evaluated on section 5.4.6.

4. Check experiments shown at Fig. 5.33 to 5.35. Videos of these exp. are
on the Dropbox link. If one tries to levitate this magnet with induction
the magnet would be hot enough for not to  touch after a while.

5. I also tested inductive repulsion on conductors like iron, steel or
inox. They become hot before get repelled some. One can try it by putting
an inox piece on a balance and inductively push it.

6.Again contracticting to inductive force, one needs lower rotation speeds
to levitate bigger magnets. A 100 gr magnet can be levitated with a speed
between 2000 - 3000 RPM.


Beaty: So Hamdi, are there any "Levitron" analogous effects?  Can you run
this at

*50,000RPM or something?  Does the restoring force get any less?  Or,
toproduce an energy-well, must the levitated magnet be free to
slightlyvibrate?  (Try motor-assembly placed in a plastic pipe w/air pumped
out,so motor-watts during the extreme RPM need not be enormous, if no

The exp. on Fig 1.1 is running at 105000 RPM.
Despite the repulsion force is inversely proportional to speed squared it
is also inversely prop to moment of inertia (MoI) of the levitated magnet.
Since the MoI of this magnet is so small, it allows to obtain an enough
repulsion force at this speed.
