Permanent Magnet: ON/OFF Mechanism...

[IcyBlue]

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?

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.
