Marks ring of power ..again

After I recently did read this Perpetual Holder replication:
http://www.keelynet.com/energy/emery.htm
Also I did read the Ed Leedskalnin's magnetic currents booklet

If you ask any electrician what is the device built by you, the
answer will be without doubt: a electromagnet.
However when the coils are disconected, the steel bar should be
released but this happens not.

How you have replicated the Perpetual Motion Holder I have same questions:


-If you take off the steel bar, then it is no longer attraction
between the bar and U shape and you must set the experiment again to
repeat the phenomenon. Right?.

-The phenomenon also occurs using only one coil?

-It is measured AC or DC current?

-Where is connected exactly the ammeter?

-When a many turns coil, as those on the Perpetual Motion Holder, connected
only to a DC source is suddenly disconnected produces a high voltage
peak noticeable by big sparks. The Perpetual Motion Holder not?

The effect is probably caused by remanz magnetisation of the core.
When you shut down the coils the remanenz in the cores keeps
the magnetisation flux density of the steel core at the B(remanenz) level,
so the cores and U bars keep sticking to each other.
If you remove then the cores from each other, you induce a voltage spike
into the coils, cause you change the flux density level inside the core,
which will induce a current and voltage spike inside the coils ( dphi/dt ).

This is standard electromagnetism with steel cores,
nothing to wonder about...

Thanks Stefan, I agree with you that a remanence effect (http://en.wikipedia.org/wiki/Remanence) explains pretty well all tests on the Perpetual Motion Holder. However the experimenters seem suggest (not explicitly, therefore leaving space for doubt) that when the closed magnetic path is broken (taking off the steel bar) the remanence suddenly disappear.

No one talk about sparks when the coils are disconected.
Perhaps the coils are parallel connected such that the back EMF is cancelled between them still afterward the DC source is disconnected... Or really the induced magnetic field not collapse while the magnetic path is not broken?

How you probably know, the Krepelka website is very influenced by the Ed Leedskalnin ideas. Infact the Leedskalnin's booklet (http://www3.sympatico.ca/slavek.krepelka/exper/magcur.htm) suggest rotate a magnet inside the perpetual motion holder to generate electricity. Krepelka's generator is also a magnet (rotor) rotanting inside a core closed (stator) (http://www3.sympatico.ca/slavek.krepelka/ttf2/fields8.htm). I guess the stator of Krepelka is equivalent to Pepetual Motion Holder of Leedskalnin.

I wonder really there is something special about the closed magnetic paths or only it is a misunderstanding of the basic electromagnetism concepts.

I hope Scott would answer us some questions with his replication.

To get more out of the pmh you only need to move some iron near it or just take it for a walk with a meter connected...If you move a magnet near it it is a generator.
When the battery is suddenly disconnected a large spark does jump out...
I have utilised this effect in the following way....
I made a trembler switch that is turned on and off by 1 of the prongs of the pmh..
The switch is on the pos input wire....which then goes to the pmh coils.
The neg input goes straight to the pmh coils..
Now i connect 90v neon bulb to pos side of input and the other leg goes to pos input of a car ignition coil....Neg input is also connected to ignition coil....
Pos output of ignition coil is connected to a small flouro...via 4.7uf 400v cap....
Neg wire from ignition coil goes to a seperate load, or can be connected to flouro on the neg side of the cap.....
Now when the power goes on, in this case 3v @ 500ma, nothing lights up at all because no power can cross the 90v neon bulb, but the pmh becomes a strong electromagnet and thus opens the switch....The high volt spike from the collapsing coils crosses the 90v neon and enters the ignition coil and lights up the flouro...
I also use the pmh to run a motor and the light bulbs do not effect it in any way as they only run on the collapsing spike....The loads run with un terminated ends, or open circuits, but of course can be closed like usual.
I also place ignition coil in front of 1 prong of the pmh....(when not running a motor)
Will make a drawing if anyone is interested.....

Hi Scotty1,

this sounds interesting, could you please post a drawing of your experiments ?
