Acoustic magnetic generator.

[itsu]

Acoustically heated glass can become conductive.  Are there permanent melt marks on the glass table?

Yes, there are some "pits" in the glass where the glow was seen.

This is a well know problem with piezos.  See this video.
Also, wires that you soldered to the piezo are too thick.  I use sub 0.5mm flexible stranded wire for a 5cm length and join/solder them to thicker wires for longer distances.

Great tips, i have some pieces now where i can practice on

Just a couple of random thoughts:

I was thinking that what we call the lines of magnetic force are in fact standing waves. I.E. a magnet acts like a tuning fork in the aether which
causes the lines to appear at certain locations.

I did a search on this but could not find anything but came across a link that you may be interested:

Might I suggest shying away from ferrite based magnetic field guides. I have found more often than not playing with very very similar setups that conduction within the material is very important. While the ceramics are excellent with respect to acting as a wave guide for acoustic compression and rarefraction, they are poor with respect to transfer of a magnetic field when the material length is far greater than its width. I have several detailed experimental setups which suggest that this could very much be due to the lack of electrical conductivity. There are many reasons for this, and it was extended conversation I had when i was shortly in touch with Eric Dollard. Unfortunately neither he nor I had an adequate reasoning for this result.

Another method I have used with great success is to take two very large ceramic magnets (mine were about the size of a video cassette), and give them a tap with a very hard slightly heavy object to induce an acoustic "ring". Record this frequency for each. Build an exciter circuit at the resonant frequency of the first. Take the second and shave material off of it till it has a frequency difference from the first. Now create an exciter circuit for the resonant frequency of the second magnet. Place a coil around each of the magnets in orthogonal orientations so they are not mutually coupled. When electrically excited at the resonant frequency, the reaction from the oscillating magnetic field will place the exciter into a very high impedance mode and it will be quite efficient. The acoustic excitation of the macroscopic and molecular structure of the magnet will cause fluctuations within the magnetic field. The superimposed fields from both magnets together will create a beat frequency at the difference of frequency. F1 minus F2 = F3.

Build a large pick up coil (large in diameter, and somewhat flat) with loose coupling to the setup. For example, if your magnet setup is one foot by one foot by one foot, create the pick up to have a diameter from 2 to 3 feet. (you will have to experiment. If you take into account wavelengths of F1 and F2 and F3, along with other factors such as the quarter wave relationship with respect to Lenz reaction, you will be able to figure out exactly what you need, but for starters what I describe is a good point of beginning).  This large pick up coil should have a resonant frequency equal to the beat frequency, and when power is drawn from it, it should have filters with maximum blocking impedance at the frequencies of F1 and F2. The two initial frequencies are blocked, and the created frequency is not. Happy experimenting with the missing fundamental generator!!!

Thanks MP,  interesting link and info.

Great info, so i will try to avoid ferrite as the loop back medium and use some steel.

Wow,  - "the size of a video cassette"-   those are massive magnets, and it seems this is a totally different beast.
You  must have i nice workshop when you are able to  "shave material off of it".

verpies mentioned also to try to "ping" the used ferrite rods to see how long and at what frequency the ring.
I still want to do that.

Thanks for your input,  regards Itsu
