Self running coil?

[gotoluc]

Hi Luc,

Thanks for all the tests, I am even more puzzled now... and this is not a complaint of course      

Basically I meant to get rid of the hi res Fluke microvolt meter because I suspected its ground sees the computer grnd and the signal gen grnd and at the same time it has to measure a few microvolts amplitude floating on 12V DC  while the pulses has an increasing frequency: this may challange its common mode behavior and the sampling process inside it may suffer.

Well this is not case, so for the time being I have no explanation (of my own) for the negative polarity...

Thanks,  Gyula

Okay Gyula I understand.

I have tested ground loop possibility before and found none.

However, just to make sure again I connected the high resolution volt meter to an inverter so it is powered by 12vdc (no ground possibility) and the current meter I used is a battery operated one so that's not a problem. There is no Oscilloscope probes connected either, so that's not a problem. The circuit is running from one 12vdc battery and a separate 12vdc battery is used for the inverter to power the volt meter.

Still with all this the results are identical as I posted.

I think it maybe time you consider this as a true gain of current when the magnet is applied and resonance is achieved.

Let me know if there is anything we could of missed.

Luc,

Then a logical step would be to go up in the resonant frequency in this setup, this means to lower the inductance further down with stronger magnet(s), right?

What if you replace the 12V battery with a capacitor, charged up first to the same 12.7V?  If current flows back then the cap voltage should very very slowly increase (depending on self discharge inner dissipation).

This is what I have been doing ever since I started this topic Gyula.

No battery is connected and the cap bank charges up.

very nice.

Hi all, I did some tests based on some comments in this thread to satisfy my own curiousity.  Dont know if its useful or not, but here are the results.

Core: Metglas 2714A 2510P4AF Flat Loop  25mmx19mmx10mm flat loop

Magnet wire - 22 guage

BK 878A LCR Meter

4 turn wire - 12"

2 turn wire - 6"

1 turn wire - 3"

Data is at: http://spreadsheets.google.com/pub?key=twYJTFuWUrRAMMzos--b_LQ&output=html

I dont know if there's anything useful in there yet - I was just recording data.  One thing I saw was the discrepency between the 2 CCW + 2CCW series and the single 4 CW - I wound those setups twice to verify that it was different.
