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 airturbulence.)* 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. ========================== On Thu, Sep 10, 2020 at 4:23 PM William Beaty <bi...@eskimo.com> wrote: > On Thu, 3 Sep 2020, Terry Blanton wrote: > > and suspend it in the spinning magnet's field regardless of the > > polarity of the stationary magnetic.
