magnetic spinning disc video

What does the word quote do on the web site? Anyone please

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?

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!

I wrote a couple of replys

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
