Please disproof this video- it could be a hoax

Hi Hel,

I can assure you that the tests shown in those videos are NOT a hoax.  (I know the person who did those tests several years ago.)
(here is the second part as the continuation of the tests:  http://www.youtube.com/watch?v=fJl0TO_aR6M if you have not seen it)

These tests have been a topic here:

I think the huge DC current pulse (must be well over 15-20 Amper or even higher, coming from a 12V battery)  rearranges the domains of the cores and depending on how good a core is (from remanence magnetism point of view)  the domains need a certain time to return to their original state.  I believe this RETURN movement what is sensed in the shorted coil as a 'continuous'  current (that is going one direction but its value may be fluctuating) what is interrupted  when you REMOVE the shorting wire from the coil, this interruption then causes a further flux collapse that helps domains much quickly return to their original state.
This is how I see this.  MAybe some other factors yet unknown to me also play a role.

I wish he would place a 12V Bulb across the coil of the Taped Core
to see if it STAYS LIGHTED.

What he is showing implies a CONTINUOUS CURRENT in that coil.
Is it possible he has an Overunity Device?  It sure looks like it.

Thanks to all for the links.

Wringing seems all another matter, having nothing to do with magnetism. I.e, the same thing when you put two
flat smooth glass pieces together, they stay stuck.

The experiment using the two steel blocks with the rail for the current carrying wire is nothing strange, it's
pretty the same as the PMH effect, just with a different geometry. I also see nothing strange about the fact
that no magnetic field is detectable outside once the blocks are stuck, since the magnetic field holding them
together is completely enclosed - just like inside a toroidal core, or a Leedskalnin's PMH with the keeper
attached [in general, I suspect the PMH effect has nothing or little to do with residual magnetism or hysteresis
loop of the material, since it's just about the domains remaining aligned in a closed loop. Still it's nonetheless
something few understood, since as I said some magnetic materials show the effect while others don't. But
this is not the matter now]

The fact of using a secondary coil which would apparently "keep" the magnetization in form of persisting
current is another matter. I of course don't want to mean that the author of that video is necessarily fooling
us, I may suspect that himself was fooled someway instead. It's about something which is worth investigating,
since you all realize the implications...

Since yesterday I went on experimenting but I could not replicate the effect. Ok, as I said I have no such
tape-wound cores. My experiments with ferrite cores still seem suggesting what I had explained, i.e some
residual magnetism (and/or veeeery slight PMH effect), after insisting with the magnetizing current, and
any tiny movement as the act of disconnecting the secondary causes the lower piece to fall apart.
I had a 0.01 Ohm shunt resistor closing the secondary with my scope across it to measure current.
No stable current, no remanence. Just the spikes of opposing polarities when turning the magnetizing
current on or off, as anybody would expect.

But, IF EVEN some remaining current was possible in the secondary, perhaps using tape-wound cores
or other special materials, it would require a very low secondary resistance: i.e any load put there, as
a light bulb, would just cause this current to dissipate faster, increasing the resistance.

In addition we should consider the directions of the induced current.
Assume we use a clockwise magnetizing current in the primary to induce a flux with some direction
inside the core. The induced current in the secondary will be counter-clockwise (-di/dt), and if
such a current could persist (like in a superconductor) it would sustain an opposed flux in the core
to the one we tried to impose. When we break the magnetizing current, then a clockwise current
would be induced in the secondary, this time sustaining (if it could persist) the original flux direction.
A bit puzzling...

...btw, Gyulasun, I think your explanation may be the most sensate. A very delicate interaction between
relaxing domains and the "feedback" from the closed coil. Definitely no stable or less stable DC.
A pity that the author seems not so interested by the effect he discovered.
Firstly, he should check furtherly the replicability (i.e if the act of opening the secondary coil is more
or less statistically related to the piece falling apart).
Then, he (or anybody else provided with similar tape wound cores) should check with a scope what
kind of current is circulating in the secondary coil (possibly using a very low resistance shunt as I did,
even lower)

There are a bunch of those experiments with flux lines, those aren't faked at all, in my opinion.  We where recently talking about those and a few others on the 5Kw TK forum. They are very interesting and a good source of information.
