Getting Through Stickey Spots?
« on: July 02, 2007, 08:12:52 AM »
Ive been doing allot of research and think but am not sure on how to get around magnetic stickey spots everyones been having.

In a hard drive there is magnetic shielding this shielding I believe is called MU Metal. I think it's there that way the magnet in the drive dosent F up the electronics. On all of the videos Ive seen the shielding has been added to the magnets on the rotor.  But what if you added it to the fixed magnet? That way it's only pulling one direction.

 What do you guys think?

Theres only so much you can do with it, but try different configurations out.  No one here has the answer otherwise we'd be cashing in :D  I was pondering the idea of trying bismuth discs into the configuration.  Bismuth so I've read can be heated and poured, to make your own custom shapes.  I've just been thinking lately that a magnet motor might take metals and other materials besides just magnets.

Theres also another problem I've run into many configs.  After about 120 degrees the magnetic field starts weaken.  I think perhaps a device divided into sections at a minimum distance from each other so as they wont interact and cause ill effects.

If you want to block magnetic fields there's also a new material I found via this forum   - graphite made by chemical Vapour deposition. I can't find the site page now - i think it was Scitoys . . . but the stuff is so diamagnetic that it will float above both N and S poles and its available online relatively cheap unlike bismuth.
OTOH, I don't know wether it will really make a monopole just by blocking the field of one pole - try it and let us know!

Guys,

Magnetic shielding (a poorly understood misnomer in itself) has been tried by dozens of people in dozens of ways. If it was easy, it would have been done by now I would think.

But try it anyway. See the effects.

Darren

Check this link out. It's a material called Giron that has some very interesting properties.

http://www.lessemf.com/mag-shld.html

It's $35 for a 2'X1' piece. It can be cut. A bit costly, yet seems like a very useful addition to ones magnetism experimentation lab.

the keyword here is ELECTRO-Magnetic....Mu-metal and Giron are effective for their intended uses, but rather hopeless for effectivley sheilding P.M. I have  had some luck with surrounding P.M. with a powdered iron matrix, but don't know yet what the long-term effect on the magnets will be. (Probably not good.) The only sure thing I have found is separation. Working on a new idea now.

Hi Folks,

There is an interesting property of Giron which I think is important for effectively use Giron as a shield, see this text from this page: http://www.lessemf.com/mag-shld.html

"A further distinction is that the magnetic properties of GIRON are anisotropic... that is they are not the same in all directions. Permeability along the long axis is excellent, across the long axis good, and perpendicular to the surface it is slight. Thus magnetic shielding effect can be increased or decreased by merely rotating the orientation of the shield. Very unique!"

Somehow this property could be utilized for our purposes here, by good mechanical arrangement and selecting thickness, magnet sizes etc.

There is another material called Pyrolytic Graphite, (PG), see this link:
http://scitoys.com/scitoys/scitoys/magnets/pyrolytic_graphite.html

This could also be used for shielding and also has got similar property like I referred to above in case of Giron. PG is available from Scitoys.

Finally see this link for another magnetic shielding material (described in the US patent):  http://www.overunity.com/index.php/topic,2217.msg29095.html#msg29095

Because neither pyrolytic graphite nor the mixture material from the US patent is attracted by permanent magnets (they are non ferromagnetic, unlike mumetal or Giron) they may serve better shielding materials for our purposes here.

Gyula
