Deflecting magnetic field shield

[smith]

I am not a physics major, but isn't there some rule about equal and opposite forces? Unless in the quantum world of electrons and such, these
rules are different, I don't know. When I take a strong neo magnet and quickly pass it by the patent mixture, should the mixture (As
a pile of powder) somehow react to the magnet swooping by (Aside from the coal slag having some ferrite content). I would expect that it should
be either momentarily be attracted or repulsed, or make some movement, besides from the wind passing by as I move the magnet. I see no
activity when doing this test. All I see is some of the coal slag stick to my magnet.

I tried again tonight to talk with Mr. Wadle regarding his magnetic deflector material patent and I managed to get him on the phone.

Great work wattsup on contacting the shielding inventor.
Interesting reading on your (and others) conversations with him.

I guess the xxmm$ question(s) is(are):
1. how effective is the shielding
2. effect duration
3. complete fabrication techniques
4. documented proof of the effects

Does it work?  Is it practical?
If anything, I would venture a guess that it might shield a relatively small % - like 0.1% or something.
Meaning - it would TECHNICALLY work, but not PRACTICALLY.
Further details and concrete evidence and results would be needed.

As to Lucys' post of the patent application:

Thank you Lucy for posting it.

The devil lies in the details.
As such, I find it to be short on details and long on generalities.

A few to address: (my comments in bold)

[000051]   The present inventor is the first one that thought of the idea of placing a movable magnetic shield between a stationary magnet and a stationary conductor in order to expand and contract the magnetic lines of flux crossing a stationary conductor to produce electromagnetic potential and generate the electricity.

This is the major basis of the patent.  However, he is NOT the first one to think of/present this idea and there are many documented examples of others pursuing the same methods.  A few examples are on this website.  The guy using washers as shields in this manner comes to mind (anyone remember/link to that thread?)
As such, attempting to patent a process that has been previously documented/disseminated is not possible.
And though I haven't done a patent search on this, I would guess there are existing patents that - at the very least - would have to be refered to.
Was a full search done by a professional?  Were previous documented disclosures of this process considered?
I suspect approval would require elimination of this paragraph.  But then, it's really the basis of the application - so I see the whole thing as a no-go.
(not trying to shoot you down - just stating the facts as I see them and in my opinion)

[000054]   The present invention contemplates the use of any type of non-ferrous shielding material, such as the one described by Robert C. O'Handley in Modern Magnetic Materials, Principles and Applications, John Wiley & Sons, New York, pp. 456-468, which provide nanocrystalline magnetic alloys, which are particularly well-suited for rapid switching of magnetic flux. These alloys are primarily composed of crystalline grains, or crystallites, each of which has at least one dimension of a few nanometers. The entire disclosure of each of these disclosures is hereby incorporated by reference into this specification.

Further information on this shielding material would be of great interest.  Anyone have links, .pdfs, notes etc?  Will it actually work in the manner required/proposed?

[000055]   Other non-ferrous magnetic materials having particularly useful properties are formed from an amorphous Co-Nb-B (cobalt-niobium-boron) alloy having near-zero magnet-obstruction and relatively strong magnetization, as well as good mechanical strength and corrosion resistance.

Further information on this shielding material would be of great interest.  Anyone have links, .pdfs, notes etc? Will it actually work in the manner required/proposed?

[000056]   The preferable non-ferrous material for the magnetic shield according to the present invention is the one described in US Patent No. 7, 220,488, entitled “Deflecting Magnetic Field Shield” by William May and Gordon Wadle. The entire disclosure of each of these disclosures is hereby incorporated by reference into this specification.  Examples 2 and 3 of the patent clearly show how a magnetic shielding material can deflect or block the magnetic lines of flux.

And now the heart of the details, the Wadle shielding.  But does it actually work and is a generator using it practical/possible?  (see my earlier post)

[000057]   The main advantage to the shielding material is that it is non-ferrous; thus, there will be no loss of power rom the magnet(s) when used next to the shield.

Yes - it is the (as yet unachieved) holy-grail.  This is a extraordinary claim REQUIRING extraordinary PROOF.

[000058]   Another embodiment of the present invention contemplates the use of semi-ferrous materials for the magnetic shield.

Materials like... what?  And then you have the, as still to this day, the problem of the ferrous material shielding being attracted to the magnet requiring large energy input to break it away.

Thanks again for the posting Lucy.

I look forward to further information from anyone that may offer it.

In response to the Giron material that OscarMeyer mentioned. I purchased some of that some time back.
It is a high carbon steel material that has wood grain like structure to it. If you take it apart, exposing the steel
inside, it is layered in 90 degree fashion. The steel pieces themselves will crack if you bend it in one direction,
and be more durable in the other. So the two layers are 90 to each other. It is probably useful for shielding some
limited applications. I have no use for it beyond the initial playing around with it that I did. Perhaps I am twisted in my
thinking about what I think I need to be useful, but that would be a shield material that blocks the field without behaving
like a ferrous metal otherwise.

I understand this thread is rather old, but I stumbled on it today. I'd like to set the record straight and point to the fact that the product you can buy in the States called Giron is actually G-iron Flex, produced by G-iron Srl, an Italian company. The company's core business is the development and installation of shielding system with their proprietary technology to protect people and sensitive equipment from the effects of the magnetic field. G-iron Flex is as of now the only magnetic shielding material that is still efficient when bent to a 90-degree angle. Visit http://www.g-iron.it/en to read more about it.
