What is still a question is how the 11mm push is measured over that distance, with the wheels' magnet aligned in the center, or with it passing by.


The answer is posted at the correct topic of discussion: http://overunity.com/16987/td-replications/msg499732/#msg499732


Sorry Floor for the off topic posts

Yeah, Floor, sorry. I was lured into this off topic stuff ^^
Just this: Conrad, face it, your lamp comparation is silly. Light a lamp for an hour, the light and heat energy output will be half of two hours, no matter how fast you throw the lamp out of the window. Or something.


So lets get back to shielding, that I am personally very interested ATM. Thanks Floor, very interesting.


The problem I am currently confronted with is that a shield will adopt a polar axis that is aligned to its shape, usually 90deg to the magnets axis. In my particular design this leads to the undesired sideeffect, that an approaching shield is repelled by the coils reactive field:
pm:
N
S
shield:
    <<<N===S
coil:
N
S (due to decreasing primary fieldstrength by progressive shielding)


Which I try to overcome with a big, ultrathin PM at the bottom of the shield, facing NS downward. Unfort. I didn't find useful magnets on ebay, maybe see also my "Buddy" Thread.

Exactly what I am saying, nothing more an nothing less. It matters whether you switch on the light one hour or only half an hour. This is my point and you repeat it like I said something else. Strange!

And this is not off topic. It is very important what one compares when calculating input and output POWER (or energy).


FORCE

WORK = FORCE * DISTANCE

POWER = WORK over TIME


And one compares output-POWER and input-POWER (not FORCE and NOT WORK).


I know, some do not want to listen, so be it.

Greetings, Conrad

Please note, I have already stated that I need true measurement data to believe a device is OU. I do not just believe a device is OU until I have the measurement data to prove it or the device is running on its own and I can witness it. So please stop judging me that I just want to believe in OU as I have made no claims of OU.
Stick only to what has been presented and keep your personal opinions out.
You should know this to be the correct scientific approach.

Luc, you seem to understand what proof of OU means. I am sorry, that you were the victim of my offhand remark.

I was talking to Floor who steady fast claims OU. And I have the feeling that Dieter also claims OU and many others.

My only point:

One has to compare input-POWER and output-POWER, which brings TIME into the equation.

One should not compare FORCE and also not WORK.

WORK has to be done for some TIME to generate POWER (or energy).

I made an error last night, which is confusing. But my point now is crystal clear and the truth.

See: http://overunity.com/17097/magnet-force-shield/msg499715/#msg499715 (concerning POWER versus WORK, TIME is of the essence)

Also see: http://overunity.com/17097/magnet-force-shield/msg499638/#msg499638 (concerning a magnetic shield)


This is not my opinion, I am stating facts which nobody with a bit of brain will deny.

Greetings, Conrad

@ all readers

Here is my most recent video.  It demonstrates the nearly free rotation of
a ceramic magnet while that magnet is immersed within the field of six other magnets.


        @           http://www.dailymotion.com/video/x5ckdkn

                          Also

The video demonstrates the failure of one of my designs which was intended  to
shield one magnet from a second magnet by use of a third magnet / magnets.

Please also note that while this form of shielding was not effective....

Both Gotoluc and my self  have had ... and clearly demonstrate very effective
neutralization of magnetic force actions in several videos.

                   
...

Scientific convention holds that some form of magnetic shielding occurs between  magnetic domains within
permanent magnets. 

These magnetic shield regions within a permanent magnet are given the name "Bloch walls".
                 
                                  I don't know....but
It seems probable, that the shielding provided by Bloch walls has the same kinds of limitations...
in terms of vectors of right angle directions of approach .....  in relation to specific polar alignments...
which we have encountered in our permanent magnet experiments.

But also, I am in the early stages of / developing a model for a different shielding method,
which is based on a model / modification of Bloch wall shielding.

I have nothing to present of that new model at this time, as it is incomplete.

                    thanks all

You're probably given up too quickly, Floor.


Use Femm for shield tests, saves time and money.


I for myself found just another loophole. I would like to tell it, but usually being carefully ignored, this forum makes me only depressed, so wish you all the best Floor.

I've used FEMM alot myself. Also done practical experiments that confirms simulations in FEMM. There is only one thing I miss about FEMM and that is the 3.rd dimension. Take a ring-magnet that is polarized radially. If you make such a magnet in FEMM, using for example 36 magnets, one for each 10 degree, in a ring, and polarize everyone pointing north towards the center, FEMM does not show any useful flux-lines, and does simulate that there is next to no attraction to a magnetic material such as an iron rod, but a practical experiment does for sure influence any magnetic material.


Speaking of shields: A shield will steal that gain you want. It doesn't matter if the shield is iron or another magnet. It shields or guides the magnetism for a reason. If one could make a magnetic shield that isn't magnetic, it would work, but that kind of material is hard to find. I don't know of any matarial with those properties.

@ All readers

I threw up..... a new video.
It shows an effective magnet shield in action.

http://www.dailymotion.com/video/x5eg7kk_magnetshield-1_tech

As far as I'm concerned, this is all open source and public domain.
All in common...that's the only real over unity there is. 
              Thanks for every thing Luc.
                 Peace... Out

@ All readers

note.. the two magnets that are glued together to make up a single larger shielding magnet,
are like poles on the same broad face as one another.  The are in mutual repusions at their edges.

Notice that in this last video, the shielding magnet sticks out
above the two stacks of magnets.

Magnet attractions and repulsion are not in all respects / situations equal in force.

When I flipped the shielding magnet over, reversed poles on ,  the device did not function as well.

That little bit of "stick out" by the shielding magnet, helps to balance the
attracting and repelling forces, I think.

There is no such thing as a magnetic shield. If there was it would imply that a magnetic monopole exists and despite the best efforts, no such thing has ever been discovered.

Quite frankly you are wasting your time trying to arrange ANY combination of existing permanent or electro magnets and expecting to create magnetic shielding. You can determine the truth of this by using Noether's theorem. "For every differentiable symmetry of the action of a physical system has a corresponding conservation law".

Magnetism IS described by a 'differential symmetry'.  'Differentiable' implies that lines of magnetic potential have no inflection points. I.e. no matter how sharply the lines of magnetic force change direction it NEVER becomes a single sharp point.(as such a point would imply a monopole, which does not exist).

If you want to create OU using magnets, you'll have to devise a way to 'pipe the magnetic field into another non-physical dimension.. good luck with that. If could do that an OU motor would just be the start of some rather interesting (and dangerous) effects...

This is actually a good insight, except that this additional dimension may not be completely non-physical, once we consider spreading of magnetic field within condensed phase instead of just vacuum. In this extent the Nassika's drive may be relevant: this thruster supposedly works like the nozzle for magnetic field, where the superconductor serves just as a magnetic shield. And superconducting generator of Andrew Abolafia could work as a Nassikas drive attached to a flywheel - or, well, sort of...

So I'd never say never: we can never know if some crazy idea cannot be crazy enough for being actually true.

Did you watch the video / videos ?  @  http://www.dailymotion.com/video/x5eg7kk_magnetshield-1_tech

Although you have not directly stated that I am presenting a "magnetic shield", you have as much as
done so in what your quoted statement (above) states.

I HAVE NOT USED THE PHRASE "MAGNETIC SHIELD" IN THIS TOPIC...
             except to say that I have not used that phrase.

It may be, that there is no such thing as the MAGNETIC SHIELD you are thinking in terms of.

The devices presented in this topic, prevent action by magnetic forces,  by means of creating a balance between
attraction and repulsion.

They do not block the magnet energy, rather they prevent physical action by the magnets , in specific vectors
while allowing physical actions in another or others vectors.

Please be so kind as to understand the presented materials before commenting next.

            best wishes
