Acoustic magnetic generator.

Now what is the sound wave going to look like to the molecule?  It will "feel" like a slightly "tighter squeeze" with the neighbouring molecules for a brief second.  That's not going to affect the spinning valence electrons.  They will continue to spin in a plane that is perpendicular to the magnetic field.  None of that geometry will be affected by the sound waves.

The magnetic properties of many ferromagnetic materials are affected by sound pressure.  It is called the Villari effect.

Why people do these things is anybody's guess...
The conduction of sound waves directly through the core, or in the air around the core will no nothing to the magnetic field generated by the magnet.

I have not seen that assertion verified experimentally.  However I have seen the permeability of soft ferromagnetic cores being modulated by acoustic pressure. 

Attached is another patent that takes advantage of the Villari effect caused by acoustic standing waves occurring in a ferromagnetic core.

Thus it seems to makes sense to experiment with acoustically stimulated magnetic circuits like those depicted below:

Verpies:

Thank you for that information, I looked it up.  It appears to be an effect dependent on the specific material, and on the intensity of the magnetic field, and on the intensity of the mechanical stress.  It looked like this effect starts happening at high stress or high magnetic filed intensity so I doubt that it applies in this case.

Beyond that, changing the amount of magnetization that you have in a core material due to mechanical stress is not a way of producing any extra energy.  So it does not act as a "key" to any alleged amplification of power output when compared to a fixed power input.

From Wikipedia (for the related inverse effect of Magnetostriction):

Magnetostriction (cf. electrostriction) is a property of ferromagnetic materials that causes them to change their shape or dimensions during the process of magnetization. The variation of materials's magnetization due to the applied magnetic field changes the magnetostrictive strain until reaching its saturation value, λ. The effect was first identified in 1842 by James Joule when observing a sample of iron.

This effect causes losses due to frictional heating in susceptible ferromagnetic cores. The effect is also responsible for the low-pitched buzzing sound that can be heard near transformers on alternating current carrying transmission towers.

From Wikipedia (for the related inverse effect of Magnetostriction):

Why are you quoting an inverse effect when the topic is the Villari effect?

The Villari effect describes the changes of the magnetic properties in a ferromagnet caused by sound waves - not the generation of sound waves by a ferromagnet (which is the opposite, as in "magnetostriction").

[MileHigh]

I quoted that because it is easier to relate to.  The actual effect changes the magnetism of a core material due to mechanical stress and it will certainly obey the law of conservation of energy.  In that sense, there is nothing there, and the Norman Wooten patent and sample circuit are essentially meaningless.

Perhaps a bigger issue is does it apply here?  There is limited value in quoting a relatively exotic effect if it will not even happen in the experiment.  I am pretty sure that it in fact will not happen in this experiment.  If anybody wants to do the full check to verify that they are welcome to do so.

@Verpies,


Thanks for the hyperlink to the Gunderson patent. Very interesting reading. More similar to what Jimboot did with output windings on a ferrite core rather then over magnets like the McClain/Wootan MRA.
