Actually, you do not have to engage the disc at all.The tractor will do the work for you.You don't have to initially spin the disc with your hand. As the field strength intensifies the speed increases.

Ok, thanks.

The ring is composed of what type of magnets? ceramics? neos? or? Do their poles face towards the center of the ring, or butt up one another? sequential or opposing? (NS-NS-NS etc or NS-SN-NS and so on)

Good stuff!

Mike, if you study video #6 you can figure out how the ring is constructed.

As a matter of fact, you can make a triangle or square capture device.

Very imppressive!  Obviously there is something behind the wall that causes this effect but, whatever it is, I would like to know how this works.  May not be overunity but, very interesting as I can't imagine any device that would make this happen.  Thanks for posting this and tell us whatever you can, whenever you can.

Hi Bill and all,

I watched some of  tractormag's videos and I think the working principle must be the effect of a rotating magnetic field on a rotating permanent magnet,  rotation is syncronised to the frequency of the changing magnetic field.

A similar effect takes place in case of Nikola Tesla's rotating eggs demonstration back in 1893, at the Chicago World Exhibition.  But in case of the egg made of metal (probably copper) the rotating magnetic field induced eddy currents and these currents created magnetic fields and the interaction of the two fields caused the rotation of the egg;  in case of using a disk shape permanent magnet the rotating field can immediately interact with the poles of the disk magnet which results in rotation.  (I assume a certain amount of eddy current is also being created in the disk magnet, Neo type magnets do conduct electric currents like AlNiCo types but ceramic/ferrit magnets cannot.)

So what is behind the walls must be some multiturn coils excited by oscillating currents of differing phase and these changing magnetic fields created should influence the rotation of the disk magnet. 

Regards,
Gyula

It puts another members post in quotations, such as the post above this sentence, so people know what message you are responding to.  Is that what you meant?

I saw the reply regarding the composition of the spinning magnet in the center of the ring, but could not locate any description of  the ring magnets and/or their polarity orientation. Do you have a reference/link?

Thanks

Has anyone figured out how this works yet?  It would be fun to replicate.

I said I would let everyone know how  the disc spins Friday Oct. 5. On that date I had an appointment with my patent attorney and thought for sure, that he would give me the ok to disclose. However, he advised me I should wait awhile longer. I am terribly sorry for I was anxious to share it to get feedback. I will let everyone know as soon as I am able.

I have an idea how it works. The spin is approx 3000 or 3600 rpm, depending on 50Hz or 60Hz outlet - the effect seen in old spike wheels on US western-movies is shown in the spinning magnet, so it is easy to calculate the rpm depending on frame pr. second in the video.
The disc could spin clockwise or counter clockwise - doesn't matter. A simple electromagnet driven by a transformer behind the wall is acting on the spinning magnet disc, and force it to have stable rpm. If the surrounding magnets was powering the disc magnet, this spinning magnet would alter the rpm depending on where in the circle it's present. This is not the case in all of the videos. A video showing two spinning magnets have the exact same rpm - is that by accident? I don't think so.
The surrounding magnets is present just to force the spinning magnet to be inside a given "playing area". Case closed ;)
