I would recommend reading the whole page, it's very interesting.

I did this some time ago. Interesting indeed, but in the end the O/U has been nailed down to a flawed measurement and power calculation.

The 17x kHz are probably just a coincidence that results from the L/C values of the used transducer and coil. Before drawing any conclusions one must know the permeability of the used magnet. Then you can calculate the resonant frequency of the circuit. If this values are at hand, and a dramatic mismatch remains between the f₀ in magnetized and unmagnetized state that can not be explained by conventional physics, it is worth to figure out why.

I agree the effect in and of itself is very important, in and of itself regardless of OU. However, even if in their experiments, they did not acheive OU, there are other ways the on/off effect can be used. Not to mention, they were seeing other effects as well, lasting weight loss, etc.

    OK all, just purchased a good signal gen as I had a need anyhow. I coudn't get any conductive epoxy tho. My reasoning here was that if I use a piece of copper flashing on each side, it would replicate what the conductive epoxy would do anyhow. Not to be the case I guess. No matter what frequency square sawtooth or sine up to 2 mhz I used the floating arm above the target magnet stayed the same.
   Considering the discussion I came up with the idea that 12v at 8 watts would need a transistor in the line and use the gen to turn it on and off. Short of winding a coil that could draw the said amount of power, I cant see any other way to retard the magnetic force.
   I will still try for using conductive epoxy yet. Just have to find out where it can be found.

Why electrically conductive epoxy?
Then, the magnet inside two metalic parallel plates (inside a capacitor) is not the same effect?

[mitch]

This thought came to me (lonely thing it is)...

Rather than glue on wires with conducting adhesive, has anyone attempted to use a plated Neo magnet, and grind off the plating between the ends where wires are soldered onto the plating?

Ah! Another thought (where there's one, there's ususally more)

If the magnetic flux cancellation is induced by capacitive coupling, then a flat disk magnet, with the side plating ground off, would show less coupling energy to induce the effect than a long narrow magnet.

I am curious if any can measure the A.C. current involved when coupled, which would show a dip/peak when the frequency sweeps into and out of the coupling frequencies.

This could essentially be a magnetic domain resonance, like an NMR coupling, but with magnetic domains rather than atomic nuclei.  The coupling frequency matches the domain flipping time.  If the effect is domain related then fine-grained versed course grained ferrous domain material may show different resonant frequencies.

The magnet material volume would be another good bit of data to compare in a series of tests, to see if it is realted proportionaly somehow to volume.

...*snip* and grind off the plating between the ends where wires are soldered onto the plating? *snip*

You cannot solder a neomag without damaging it's strength. direct heat = bad

all else looks interesting.

I think using an iron wire coil around a magnet would be the easiest thing as you could use
very fine isolated garden wire, so the current would be low and just try to
toggle on/off the magnetic properties in this core-coil !
This way also the magnet will not be weakened !

Hi Tao,

This topic is immensely interesting and I would like to do a thorough investigation of the idea. Right now, I am working at my university in the physics department but as an Engineering student, I have access to pretty much whatever I need to do any testing so I want to setup a thorough experiment to prove once and for all if this does work. I want to start with ferrite magnets since the person said they worked well, but I'm trying to understand how to best attach the wires to the magnet. Do I simply touch the tips of the wire to the sides or is the conductive epoxy necessary to make a decent electrical connection... and as one person already mentioned, I wonder how this will effect ceramic magnets since they are already non-conductive.

Is there any way I could get in contact with the original person to ask him about this?

God Bless,
Jason O

P.S. I?ll also try Stefan?s idea with the iron wire also.

Hi Jason,
ceramic magnets will probably not work as they are
nonconductive.
I also don?t think, that glueing conductive epoxy plates will
have any effect on the magnet when being driven by about 180 Khz,
as it would be, like placing the magnet into a capacitor...
Okay, maybe, if you apply 5000 Volts AC peak to peak, but not
at 12 Volts AC peak to peak.....

I guess it really needs a current through a metal,so only
conductive iron based magnets like Cobalt-Nickel-Iron magnets
will work or also only steel magnets which have not a very
big coercitive force ( low Hc)...
So I guess it would be much easier to try it first with
an iron coil around a magnet, as you don?t need to change
the magnet and can see, how the about 180 Khz AC current reacts to the magnetic
properties of the iron wire.

Also you will discover probably, that you can conduct
heat from the ohmic currentheating of the iron wires into the direction of your magnet field.

This I had discovered last year, when I played shortly with an iron wire coil.
As the magnet field from the permanent magnet is "sucked" into the iron coil,
the heat generated by the ohmic heating of the iron wire is flowing
into the direction the magnetic field from the permanent magnet goes through the coil.
So the heat is maximum there, where the most flux is squeezed in the iron coil...

Also, maybe you can confirm, that iron wire coils don?t have much
Back EMF when driven with pulse waveforms.

There are still many new discoveries to make with iron coils.

Hi

I totaly agree with Hartiberlin - behaviour of coil
wound with iron wire is strange .
For example I produced a selenoid wound by iron wire
and this selenoid did not work . It surprised me.
Does somebody a theory why it is not working?

thanks
