Please disproof this video- it could be a hoax

[Hel]

I hope this is the proper section to point out this matter...
Recently I stumbled across this video:
http://www.youtube.com/watch?v=SHbQXnXK6Xc
(just skip the first part where he shows the magnetically biased transformer).

In short, the author is demonstrating an anomaly in the so called "perpetual motion holder" effect.
By using a transformer (presumeably laminated iron) double-U core, the effect is there.
By using a "tape wound" double-U core, the pieces don't stay stuck after running the magnetizing current.
But, after placing a shorted winding to the core pieces, they stay stuck as in the first example.
The astonishing thing is that, when he opens the short, the two pieces fall apart.
Well I fear he's fooling us. Please confirm and/or discuss the thing objectively.
I think this it's definitely IMPOSSIBLE, since that would imply a DC current permanently flowing
in the shorted winding, as it would be a superconductor, which breaks up when opened.

I could not try to replicate the effect because I have no such "tape wound" cores.
I made experiments with other materials not showing the PMH effect (i.e a ferrite core from a
flyback) and a similar shorted coil, but the pieces won't stay stuck anyway.

Thanks for your attention.

Hi.

I see that you have already decided what is real and possible.
I just checked it with two U shaped, big ferrite cores and the effect is there!
Our current understanding of electromagnetism is not yet complete...

We are living in a vast and dense sea of fluctuating energy fields. There is no 'close system' in reality, so the math and 'our laws of physics' apply only up to a certain level of complexity, as they are based on certain preconceived model of reality which is very basic and unfortunately flawed in many areas such as gravity, inner workings of the atom and macro scale cosmology. Try to search some info on electric Sun theory and see if it clicks

Now, the way I understand this phenomenon goes like this:

Electric and magnetic field in this configuration are closely coupled and close-looped, they are more or less contained.
If any of them is exposed to external influence that tries to change it there is a resistance to that change, as it is commonly understood by the 'laws'.
Magnetic field in that video example is very strong, much stronger than Earth's magnetic field. So if we have a dense 'conductuctor' for magnetic flux - like a solid core - the remanence is very strong for that type of core. Why is it so strong then?
To me it looks like that there are lots of 'tiny' closed circuit path for current to flow inside such cores. You could say that superconductivity exists around magnetic domains in ferromagnetic conductors.
But to me it is more like an alignment of electric dipoles of iron molecules/free electrons where somehow it is easy to close the loop for the electrical potential, where again, this circular current is being somewhat 'shielded' from the external EM fields by surrounding, dense magnetic flux.
Now, the shorted winding illustrates this theory nicely, although in this configuration the wire is not shielded from all around that it is why it breaks loose after a while.
If my understanding is sound, it would be possible for a low remanence core, such as ferrite to retain induced magnetic flux for a long period of time as in Ed's Leedskalnin' PMH, provided a closed loop conductor INSIDE the core...

Be open minded, think, and do not follow blindly any religion like contemporary science

Thank you for reply, but I'm still reluctant (pun not intended as before...

Premise: sorry, almost nobody knows me on this forum... I mostly read, and practice
experiments. So, please no need to suggest me being open minded since I'm actually more
than you think I just don't believe ghosts until I see them. I actually WOULD LIKE that
such an effect was for real. I do recognize science is incomplete and knowledge obfuscated
by math formalisms, that we actually know few or nothing of our universe laws, etc. etc.
So we mainly agree here.

But, until a counter proof, followed by scientific explanation and repeatability of this effect,
I can't believe it. I stress again that, in order for a similar behavior to be real, a constant DC
current should be able to circulate in the secondary coil, for at least some seconds before
extinguishing itself by ohmic losses - and such a thing I think is impossible at room temperature.

Now here's my update about replicating, and my thoughts.
Premised that unfortunately I have not such tape wound cores (hmmm... any hint where I could
find them without searching for a supplier ? I usually don't see them inside common dismantled
appliances or other electronic garbages...)
I have conducted more tests with ferrite. Usually ferrite does not exhibit the PMH effect, in my
experience at least (contrarily to iron, for example). But I realized now that if you insist with the
magnetizing current (i.e not just spikes, but keep it for some time, or just you insist with spikes)
at the end the two cores end up slightly magnetized, and do attract. I wonder if the same thing
happens with those tape wound materials !
I'm telling that, because that initially fooled me in believing that I had replicated the
effect. As magnetizing coil I used one with many turns, so that I could keep it energized with
12V DC for some time without burning it or the power supply. As secondary coil I started with
one similar to that used in the video, and I perceived a slight increase in residual attraction
with it shorted. Following intuition, I tried with a secondary made of few turns of very thick
wire (very low ohmic resistance, so any induced current could last longer, in theory). Well,
in the latter case I seem to perceive a stronger residual attraction, I could even lift the
contraption with the lower U still attached. And unshorting the coil, I had it dropping.
But I checked better. I tried again, unshorting the coil... this time the pieces remained attached.
It was the residual magnetization I told above. It's tiny, so that any slight movement (as the
act of disconnecting the coil ends) causes the lower piece to fall. So far, this is my suspect,
what I just explained. But it's still to be proved.

I have now to try further with different cores, and also with a very low resistance ammeter
closing the secondary coil - in the case, it should indicate some more or less slowly decreasing
current (!) and I really doubt that it's possible at all. Just not to look skeptic  !

More comments are welcome, of course...

Right on!

This phenomenon is called Wringing. Here is a wikipedia entry on it:

Wringing is the process of sliding two blocks together so that their faces lightly bond. Because of their ultraflat surfaces, when wrung, gauge blocks adhere to each other tightly. Properly wrung blocks may withstand a 75 lbf (330 N) pull.[4] While the exact mechanism that causes wringing is unknown,[4][5] it is believed to be a combination of:[3][4]

    Air pressure applies pressure between the blocks because the air is squeezed out of the joint.
    Surface tension from oil and water vapor that is present between the blocks.
    Molecular attraction occurs when two very flat surfaces are brought into contact. This force causes gauge blocks to adhere even without surface lubricants, and in a vacuum.

Here is another video of someone achieving this effect in a much simpler fashion: http://www.youtube.com/watch?feature=player_embedded&v=eWSAcMoxITw

This effect has been known of for a long time apparently. Read this page on peswiki.com about it: http://www.peswiki.com/index.php/Directory:Leedskalnin_%22Perpetual_Motion_Holder%22_%28PMH%29_Bond_Effect
