Pyrolytic graphite shielding
« on: January 30, 2009, 01:29:39 PM »
I am thinking on using this diamagnetic material to screen two same polarity neos by putting it between them.Is it a succesful material to do this?

What do you want to "screen"?
Do you want to make it so that the magnets don't "see" eachothers field?

Perhaps this magnetic field deflecting material would be usefull?:
http://www.rexresearch.com/wadle/wadle.htm
a brief quote:
"The present invention concerns a shielding material for a magnetic shield containing coal slag; silver powder; a mixture of calcium powder, magnesium powder, and zinc powder; and silica powder. The shielding material is in powder form. In another embodiment, the present invention contemplates adding nano-silver to the shielding material. The present invention is based on the concept that the magnetic field is actually "deflected" away from the area shielded.

A magnetic shield is traditionally made of a metallic material such as steel, iron, and nickel. Because metallic materials have a strong attraction for magnetic fields, the shield traps the magnetic force and diverts it around the equipment generating heat."

So in contrast to the commonly used magnetic "shielding" materials such as iron, nickel, cobalt, mumetal, etc, that
do not actually shield anything from anything but rather offer a path of higher flux permeability,
they claim this material actually deflects the magnetic field...

I will perform a process very similar to this.

Gettng bigger energy than used for moving the shield.

This is pretty similar to an early John Ecklin motor

See page 27.

Yeah you are right.It is very similar to Ecklin's design.But Ecklin's design is just a design.There is no working device.To add this no explanation about magnetic shield.It is very easy to say magnetic "shield".It is just a word.But what about it's chemical properties?

I am just searching for this material.It must a diamagnetic material.In room temperature the best (at least for now) is pyrolytic graphite.I am just wondering is it worth to do this experiment with pyrolytic graphite?

You will not need a huge amount. Why not ask these
people to send you a free sample?

I will ask a sample Paul.But nobody here tried this shielding experiment?

Sorry, but pyro graphite will not work in this embodiment. The effect is one million times weaker than the ferromagnetic effect.

I have bought the nano silver and other compounds for the other patent but have not tried to mix them and try it yet.

I would recommend you try the same and we could compare results?

Thanks,
Jeff

This is an excellent idea. Also, pull to pieces an old scrapped
computer hard drive, and get out the two Neo magnets near
the coil, and with a sharp knife, get these off the mumetal
base.

Try the mumetal as well.

Doesn't numetal stick to neos?Let's think it didn't.But numetal catches all the fluxes from the magnet so it will be so difficult to seperate from them.There must be a room temperature diamagnetic solution.

Arringtj I am very curious about that mixture.I am looking forward to your reply about it.

I also have tried mumetal as a shielding material with no success but one material that may work as a shield is bismuth.

Tropes,why do you think bismuth is the only material?As I researched,pyrolytic graphite is more diamagnetic than bismuth.(approx. four times)

Idk, didn't Bismuth become superconductive when supercooled?
Didn't superconductive Bismuth generate a "meissner" field,
reflecting any ambient magnetic field back ?
(See videos of magnets hovering over a piece of supercooled Bi)

But really, think about it... Either you want the flux to pass through the
"shield" because the flux permeability of the "shield" is much higher than
the surrounding materials, in which case the magnets would become
attracted to the "shield" and would be difficult to remove from the shield,
or you want the flux to be deflected from the shield, never passing through
it and always going around it, which would also "deflect" the flux from
"colliding" with the opposing flux from the opposing magnet, in which
case the magnets would never be attracted to the "shield" but would
"feel" a decreased opposed flux from eachother when the shield
is in place. It would seem that removing the magnets from their "shielded"
spot would increase flux opposition a bit.

right? ;)
