Title: Spherical magnet spins due to a rolling force and defies gravity!
Post by: broli on August 15, 2022, 03:48:31 PM
I came across this very interesting paper:


Spin revolution breaks time reversal symmetry of rolling magnets | Scientific Reports (nature.com) (https://www.nature.com/articles/s41598-022-17766-z)


Which shows a very interesting effect I havent seen discussed before. When a spherical magnet is allowed to roll it causes it to spin due a combination of the Barnett effect and gyroscopic precession/damping. This seems to break symmetry as in this paper they show how it can lift up against gravity. I just ordered some spherical magnets to play around this effect.


Here are the related videos:

They could just be attracted to the Fe in nearby objects. Screws in the furniture etc. I have 3 spherical neos of varying diameters they roll very easily on a bench if iron is nearby. Not sure if its Al or Fe in the clip but either would be having an affect at that distance I would have thought. They way the magnet wants to roll towards something when first on the bench indicates it is being attracted to something. Surely they would have checked that but can't see in in the paper. I can see a particle board bench which typically would have screws in it. They may be right but the vids are not convincing.

This is somewhat related.

Interesting stuff,  thanks for sharing.

This seems like a very simple thing to rule out. Especially when the magnets are rising in a glass tube. What metal object would be attracting them, the ceiling?

I hope they're right because it would be interesting to explore. The stand that hold the tube looks like it could be some metal involved. If it was just plastic and ceramic then great.

Jimboot,  I already had two spherical magnets so I posted my own test of this in a video at overunityresearch.com (Thread - Energy from electron spin) using two plastic vitamin bottles with the tops cut off.   They definitely climb up when rotated.  No other metal was nearby.  Quite fascinating.

I just took the 2 bottles outside to try this.  Now this is strange.   It took much longer for them to move up and they kept going up and down in little increments but eventually came higher.   So I wondered how this could be by just going outside.   Ceiling?  But that is not it as I went back inside and tried inside with the same result that it took much longer for them to go up and they acted exactly the same as outside - going up and down in little increments but eventually reaching the top.   Gravity stronger today?  LOL  I have no explanation for the difference I see in the test today versus the test I did a couple days ago when I made the video.   Inside test today was done in the same spot and it now takes much longer to get them to the top.  Same temperature inside.

Try to wash the spheres and containers with soap and dry them good and try again. They might have gotten contaminated by the oils of your hands and affected their friction.

I left them sitting on the counter separated by about 18" and they had not been touched since the first test so I don't think it is dirt or oils causing this change.   I will continue to try at different times today and the next couple days to see if there is any differences.  I'll try washing eventually but at this point I'm fairly certain that is not the cause of this change.   I'm considering the rather wild idea that the full moon on August 11th which is now waning might have had something to do with this.  We know it affects the tidal ocean waves causing them to be higher when the moon is full so maybe it is possible this effect will lessen as the moon wanes.   I'll be doing daily tests...

My pendulum demonstrated the spin effect over 15 years ago here
https://www.youtube.com/watch?v=4FzK2XKQ-74

Dropped at 2pm goes down and up to 12 then drops back down slowly.

Why? Clockwise spin pushed it up 2+ hrs and counterclockwise it brakes the fall - thus slowly.

Humidity is the explanation for the difference you saw in the tests done on different days.  How can humidity change the results of the test?  It's easier to induce a static charge in lower humidity than at a higher humidity level.  The magnet is reacting to a static charge induced on the surface of the glass/plastic tubes as it's being rotated!

If you don't ask the right questions, then you won't get the right answers.

Quoting from the publication found in the opening post of this thread (See first image below): "In a first approximation, we neglect all effects of moving electric charges or electric fields due to the time-dependent magnetization because of their weakness".  Shame on them for neglecting this!

Another quote from the publication (See second image below): "Our analysis shows that, when a net torque about an object’s rolling axis is minimized Tc.m.=∑Ni=1ττi→minTc.m.=∑i=1Nττi→min, the object spins up with an angular momentum LR, pointing in a direction which differs from those of the magnetic field, the magnetic torque, the rolling axis, and the net torque about the rolling axis, and starts to move perpendicularly to an applied force with a velocity vR."  Their first approximation is wrong in regards to moving electric charges, so how can they get this right? 

What happens when electric and magnetic fields are perpendicular (See third image below)?  The electrical force acts in the direction of the electric field, in our case it is the direction of the z axis. The magnetic force is perpendicular to the magnetic field which has the same direction as the x axis, so the magnetic force acts in the yz plane.  This is why the angular momentum LR, is pointing in a direction which differs from those of the magnetic field, the magnetic torque, the rolling axis, and the net torque about the rolling axis, and starts to move perpendicularly to an applied force with a velocity vR.

Another quote from the publication (See second image): "Furthermore, we are interested in the regime of rolling without slipping".  It's rolling without slipping because the magnetic force is acting in the yz plane!  They completely missed the boat based on a wrong assumption of their first approximation!  One folly (neglect of moving electric charges) leads to a greater folly (spin revolution breaks time reversal symmetry of rolling magnets).

Once again, Shame on them!

Broli,

Here's a high frequency brushless homopolar motor (https://www.youtube.com/watch?v=3wPxkPWR8SU)!  This appears to be similar to your open circuit idea!  The author of the video claims "a high frequency magnetic field under certain conditions converts empty space into energy.  The mechanical motion of an electric charge or moving electric charge, without using an electric field, creates a different magnetic field. Increasing the frequency of this particular magnetic field induces a different electromagnetic induction than the usual magnetic field of an electrical current".  He also claims this is a "reaction-less motor".

"Converting empty space into energy"?  I don't subscribe to this theory.  However, according to Distinti's gravity model (https://www.youtube.com/watch?v=5C_vrnGj5X8), all matter must consume energy to exist.  The energy or fuel being consumed by matter is the ether.  Matter consuming the ether is what we call gravity.  This is extremely easy to visualize.  Here's a video showing a magnetic levitation of a rotating aluminum disc (https://www.youtube.com/watch?v=0wz26K2cIQo) using a high frequency magnetic field as found in the high frequency brushless homopolar motor.  Is this principal consuming the ether as fuel in order to levitate and to be reaction-less?  Distinti says if you can drag the ether along with you, then you can travel at tremendous speeds.
