Acoustic magnetic generator.

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. 

But that expectation is not a good reason to assign these experiments to a trash pile. 
What if the magnetic flux density and the acoustic standing wave frequency is just right to cause NAR ?

I am pretty sure that it in fact will not happen in this experiment. 

Actually, from my experience the change of permeability under sound pressure happens in ALL ferrite cores that I have tried.
The black ferrites are better at it than the gray ones, but it happens in all of them!

Verpies thanks for your input here. You sir are a man of science.


I have to get this off my chest as a pure amatuer in this field though. I consider it really poor form to berate people for an experiment here and then go and perform the same experiment with 4 vids on YouTube  and not give any acknowledgement to Stefan's forum or some of the ideas that came from this thread. If I did that in the blogging space my career would be over.

The Magnetic Amplifier works off sound pressure. Not only did the "TK Turkey" run four Youtube experiments, he failed to generate any power in the acoustic range, proving that it doesn't work! Another "Classic kibosh" of the kind he's notorious for.

By the way, Jimboot has reported some very interesting discoveries over on the open-source-energy site:

Then in such system the piezo element should influence the device acoustically - not electrically.

In Jimboot's experiments with the iPhone, piezo and the ferromagnetic core, the piezo element influences the device electrically by acting as a capacitor in series with the primary winding of the transformer. 
Most of the time, Jimboot's piezo element does not even touch the ferromagnetic core like it would in a pure magnetoacoustic experiment (as shown e.g. here and here)

Tinsel has not analyzed the magnetoacoustic aspect if this device, because the topic was not this type of device. 
He was shown an electronic contraption and he did an electronic analysis of it.  In light of these circumstances ignoring the acoustic aspect of this device seems justified.

Tinsel's electronic analysis of Jimboot's system is correct even if his bed side manner is acerbic.

Here and here are related videos that show electronic circuits exhibiting a similar behavior. 
Note that these circuits form a parallel LC tank with the primary winding and a series LC tank with the secondary winding.


P.S.
Note that at one time the input bulb is off while the output bulb is on, suggesting an infinite O/I power ratio, but that is wrong because the light bulb on the input side is not a reliable power indicator (it is merely a current indicator).  The input bulb does not measure the input power as well as the output bulb, because it does not constitute a load itself and the MPTT rears its ugly head.

@Verpies,


Quote from above:

"Jimboot's piezo element does not even touch the ferromagnetic core".

The piezo element does not need to touch the permanent magnet, it merely needs to be in the magnetic field!


Quote from Davidson's "Acoustic-Magnetic Power Generator" patent:

"Claim 1:

An acoustic magnetic power generator composed of an alternating current signal connected to an acoustic transducer which stimulates the core of a permanent magnet such that the atoms of the magnet are caused to vibrate which in turn causes the magnetic field to vibrate and causes a current and voltage to be generated in an output coil wrapped around a permanent magnet or in the magnetic field of the permanent magnet which said current and voltage can be used for powering a load".

The Dan A. Davidson patent:

http://www.google.com/patents/US5568005


"The combined effect of the acoustic signal and the stimulating coil increases the efficiency of permanent magnet induction transformers".


Again, from the Davidson patent:


"When an alternating current signal generator is connected simultaneously to an acoustic transducer and a stimulating coil; whereby, both the acoustic transducer and the stimulating coil are located within the magnetic field of the magnet".
