Selfrunning Free Energy devices up to 5 KW from Tariel Kapanadze

Those non magnetized ferrite rings suggest that they are made out of a hard ferrimagnetic of high coercivity and remanenece.
The yoke cores used in those devices to date were soft ferrimagnetics, with remanence close to zero.

That's a big difference despite them appearing as the same ferrite material!

I picked up some Barium Farrite Tolorids on EBAY that were used for speaker magnets (BUT WERE NOT MAGNITZED YET). Not sure what the composition ratios are, but they might be worth a try.
Origanly I trird to demagnatized various sizes of Barium Farrite Speaker Magnets with a machine toll demagnitizer, (with little success). I could reduce the magnetic field considerably, but could not remove it all. (Still had around 20 gause remaining). So I looked for Non-magnitized Barium Farrite Speaker magnets, and found them on EBAY. Been about 6 months ago.

Nice find! They were commonly used in speakers. I'll be interested in your results if you build a device with them.

  Verpies: 
  I'm curious about the color as being an indication. So, what would your opinion be of this one that I use?  I'll soon open up another crt monitor and will look for to see if there is any information on another yoke core that I have, which are probably all from China.

On the working cores that you have examined, could you do a scratch test, for example scratch it with your fingernail or do some sort of test for compairson.

May be a while before I get back to that. I ordered the cores 6 months ago with good intentions, but other projects seem to be getting in the way. Just thought I would share.
