MAGNET SHIELDING

[Rapadura]

In the .GIF example above the steel ball will not pass by. It will be attracted from both sides equally

Thanks for clarifying this. So, we still in our search for our magnet with "unidirectional magnetic attraction".

Low-Q,

You are perfectly right in that Rapaduras idea will fail in its present configuration.

But I´m afraid your understanding of my shielding concept is flawed by a preconception.

The type of shielding exemplified incorporates a fully closed loop, its all about the reshaping of the  magnetic geometry,
leading the field into a current-like propagation through the ferrous multilayer.

This technology of altering a magnetic field by bending it into a constricted path is common orthodox scientific knowledge.

The trick here is not really shielding off one of the poles from the other, but instead by leading this field into a narrow path hidden behind the shielding properties.
And by only exposing one pole end area of the magnet to the surrounding, you still have a complete field interaction between north and south poles, but this north-south interaction is executed inside the shielded volume.

This way we have just confined the magnetic field to a more narrow path, and the exposed pole is still actively relating to the other pole,
we have just altered the geometry of the field structure, so that the electromagnetic visibility of one pole outside the shielding circuit is inhibited.

Additionally the use of bismuth or pyrolytic graphite is essential in the transition from the shielded path to the exposed pole area.

An example of this technology in action is The Wang Shum Ho prototype 5kW electricity generator which is reportedly powered by permanent magnets and claimed to be close to production. The team is seeking a marketing partner and offers a working prototype for viewing by financial backers.
Magnetic Shielding is used to create N pole Only magnets in this creation of Wang Shum Ho.

So on the contrary to your conviction, I believe shielding technology is the only way, all other ways are resulting in an even disposition of field vectors, resulting in zero output.

I came upon magnet shielding. Has any one tried this ?. I am going to ,but if someone has some first hand knowledge about how ..or if this works with a magnet motor I would appreciate the feed back. Thanks. 24hosting.

One thing used commonly for magnetic shielding is Mu-Metal :

http://mumetal.co.uk/

It doesn't shield but is very good at folding the magnetic field within it's own confines.

The only other way, that i know of, is to strongly divert the magnetic field using ferrites and this isn't shielding either but more like re-routing.

The LaFonte Group has some interesting videos on re-routing the magnetic field :

Hope this helps,

I hope people continue to pay attention to this subject. Magnetic shielding can be the solution to the search for an unidirectional attraction magnet.

Gwandau's statement that by exposing only the end area of one pole of the magnet to the surrounding, and shielding the rest of the magnet ("short circuiting" the path of the magnetic lines) we can attract a steel ball only from one side makes me have hope that perpetual motion is possible.

The day we can make a steel ball be attracted by a magnet when it is approaching the magnet, and not be attracted by the same magnet when it is going away from the magnet, we will have perpetual motion.

Gary,

yes, MU-metal is exactly what I am referring to, but you see, MU-metal is
just a multilayered system om ferrous material, preferrably simply soft iron.

It is nothing special or mysterious about this concept, so I am a little
surprised I am getting met with sceptisism by some in this forum regarding
the possibilities to shield a magnet field in any desired way.

My own experiments shows it is rather easy to create a simple one pole
field appearance with a cylindrical Neodymium magnet.

MU-metal does shield, it is exactly what it does by diverting the magnetic field
and re-routing in a desired direction.

The result is that when checking the shielded surface with a Gauss-meter,
it does not register anything, which is the very concept of a magnetic shield.

Thus I don´t care if one calls it re-routing or shielding since the result is exactly the same.

Additionally I would recommend you all to do practical experimenting to a greater extent
and not pay too much attention to what everybody else is saying, especially when somebody
says it won't work.



Low-Q,

your answer was unfortunately dispiriting Rapaduras ideas, since you almost made him believe what you wrote,
which obviously is based on something you have read.

If you have been experimenting with this technique yourself, you would have known that magnetic
multilayer shielding is a very effective and simple way to shape the field structure in any desired way.



Rapadura,

don´t give up that easily just because somebody contradicts you. Experiment. Get your own information.

Magnetic shielding is an art that incorporates a lot of different factors due to the complexity
of the electromagnetic geometry around a magnet.

Just by shielding one pole of the magnet in your example, the ball will not pass the magnet.

You are still confronted with the fact that the same attractive force that creates the movement
of the ball, also is responsible for the force that stops the ball and evens out the equation.

This setback to your concept has nothing to do with any inability to shield a magnetic field,
it is more a question how to harness the possibilities given by magnetic shielding.

Personally I believe that a magnetic motor using the attractive forces of the magnetic field
are facing a great deal more complications than a magnet motor driven by the repellant forces.

If you discarded the steel ball and instead used a shielded magnet in combination with a repelling concept,
I am sure you would get torque.

My advice to you is to try to assimilate the way a magnetic field relates to ferrous and magnetic
surroundings by doing simple practical experiments.

This way you will contribute with first hand experience and thus add to our knowledge.


And to all of you reading this,

I am not here to argue about theoretical possibilities, that is not my intent by becoming a member,
the reason I am here is to share my own practical experience and hopefully get valid self experienced
information based on empiric experiments back.

To have a theory is great, but it is just a theory until it is tested.

Don´t listen too much to others, test it yourself.  Magnetic experiments are booth cheap and fun!
