One Way Magnetic Shielding - The Holy Grail

[Tina222]

Just to help clear up the "tin" issue--I've worked in sheet metal quite a bit over the years, and what James is  using looks very familiar. It's ordinary roof flashing: plain old galvanized sheet steel, usually 28 or 30 guage B&S. It's used for edge-drips and rain-proofing valleys and the joints between roofs and chimneys (among other things). "Tin" is just a holdover term from a hundred years ago when sheetmetal actually was tin--sometimes--and the workers were called "tinners" for the tin solder they used. Real tin, by the way, is not magnetic.

Good evening to all.
Anybody have seen the last video posted by JR, with the wheel with six magnets and his rotor? It's not clear how they are positioned, and how is positioned the stator, for me.  Any suggests? Thank you very much. Andrea

This is the clip I was talking about:

Exactly what  i've been whining about a few messages up simple galvanized iron or steel if you think. And for the arrangmeent of the magnets on the wheel ...If you see can see it (the video) and you have the magnets then at least try to reproduce it ? ...trial and error, briefly. My guess is that the north pole is pointing outward like in every case ...

This clip is, I think, interesting, cause the wheel seem to go over the usual gap of the last magnet. Yes, I'm trying to replicate it but it doesn't work like in the video. Maybe anyone know the exact position and orientation of rotor and stator, cause the draw that Roney put in this thread too represents another thing. If you see, then, he uses a kind of aluminium cover on the stator: why?
PS Sorry for bad English.

Best regards, Andrea

Well to be honest i'm not 100% sure so i fear that i might answer wrong and there's enough people here with "their opignons".

I say write to him but he started to work again and i'm not entirely sure if he'll respond. If he doesn't then i'll help the best i can but first you should try "the source" lol.

Even though he doesn't know much more than me he's the one who played with them. And It's the initial attraction of the first magnet that permits to advanced throught the others. having a full wheel won't have the same effect ! briefly it's the damn equilibrium again...ahh well !

Good luck
