MAGNET SHIELDING

[Shakti]

How shielding works best seems to be questionable but it's worth an experiment. I have some MUmetal now and layering is no problem although I will say that one comment about MU being layered already is not true. It is single walled which can be layered. Layering may or may not be needed depending on other factors. Also, MU is a special process and it's effectivness can be ruined easily.

One point also is that shielding can become saturated, lessening the effect. Although this may take a long time which is good and thats where layering may help if needed.

Other points to address are the materials to be used for the energy and drive. I will try an assortment to see what happens.

One thing is a fact, a magnetic field can be contained or excluded depending on the application. Let's see if a "halbach" type effect can be made with shielding. I have my doubt's but I can't yet see why not. So many ideas swirling about, it's all good fun!

There is no question about how shielding works, once you understand it.  When you attach a magnet to a ferromagnetic material, the domains will align through the material or with the field.  After the domains are aligned, then the ferromagnetic material will act as a magnet. 

Attaching a second magnet with an opposite pole to a ferromagnetic material will align the domains parallel with the surface of the material, and the flux will travel inside the ferromagnetic material (the metal is now acting as a return path for the flux).  As long as the ferromagnetic material isn't fully saturated, then their won't be an external field on the other side of the metal.  This is magnetic shielding.

It takes two opposite poles to shield properly.  This is an easy test for anyone to do.  The mu-metal found in the hard drives have a single magnet attached to it.  This single magnet has both poles on either side of the magnet, thus there is no field on the backside of the mu-metal in the hard drives, and this is how they do the shielding with a single magnet.  If your magnets are axially magnetized, then it takes two magnets.  Don't make this more complicated than it really is.  The concept is simple, and shielding does work, but you must know how to do it properly.

That was a very nice explanation Gravityblock and I woudn't dream of making something more complicated than it really is.

With respect, it seems you have made my comment more complicated than it really is. If you will please notice I wrote how shielding works "best", not how does shielding work. My questioning comment was simply aimed at the best method of applying shielding to the subject of a magnetic overunity engine, nothing else. I'm sure you can see that now I have clarified my meaning

By the way, I visited a factory that makes and fabricates the MU yesterday and had quite a nice chat with one of the men there. For all those trying shielding with MU, one bit of advice was given to me that it should not be droped as doing so can knock the particles out of alinement resulting in less efficient shielding. It's quite an interesting process they use to make the stuff.

I have different sizes of MU now and other materials to do some testing. I have my doubts for various reasons, but it should be fun.

Welcome to the forum Shakti.  Please keep us updated on your testing.  Thanks.

Thank you GB.

The main obstacles I can already envision is that although MU is a shield, a magnet is still attracted to it being what it's made of. So, even if a magnet is shielded to allow another to pass the "sticky" point, the attraction to the shielding may cancel out the action of polarity.

Anyway, I have another idea to overcome that so lets see what happens:)
