Self running coil?

[mscoffman]

By the way, i think the most optimal core would be a 'pot core' like this:
...
Such cores have the lowest losses, are also closed like a toroid, but even
more closed  and the coil can be wound very easily because it's a normal
coil, you can wind it with a drilling machine in one minute. The magnets can
be placed on the outside.
...

@skywatcher;

I like this idea, not only is the toroid on all sides...External interference
can't make it's way inside...nice for applying to a working overunity
circuit for finding whether excess energy comes from outside or inside
the toroid core material.

BTW, If you get a "Red X" when you click on skywatchers second

picture?...anomalous+bogus.

Hi everyone,

NextGen67 suggested a test to which I had not done yet.

He suggested I test the single winding toroid with a magnet but dropping the inductance to half and also do the same with the dual coil toroid.

To my surprise both torois resonated at the same frequency.

So I decided to try them at quarter inductance and eighth inductance. Again they are very close.

Seeing these results I would now say that it is indeed the magnet that was causing the large difference in resonating frequency between the two toroids when tested one with magnet and the other without.

This could be easily explain:
The magnet causes a compression on the toroid, which could be like adding a bungee to a swing and the other one nothing. They will have a different resonating frequency. As you can see in the scope shots below, the more magnet flux is applied (stronger bungee) the higher the resonating frequency is. However, keep in mind that we are also lowering the inductance value which is the main reason of the increase in resonating frequency. The differences that I'm referring to is the 2KHz difference between resonating frequency of the two toroids tested (one with magnet and the other without). This is clear to me now and I hope it is for everyone else! since when the magnet is on both they become quite similar.

All tests are using 12.86vdc and IRF640 as switch, triggered by signal generator and tuned to send most current back to source. The green scope probe is between drain and source and yellow probe is between gate and source.

In this post I attached the two shots with magnet to drop inductance to half.

Notice the bonus of extra magnet flux but also with the extra inductance of the dual coil

First shot is of dual coil toroid at half H returning -8uA and next is single coil toroid at half H returning -7uA

[gotoluc]

First shot is of dual coil toroid at quarter H returning -22uA and next is single coil toroid at quarter H returning -14uA

[gotoluc]

First shot is of dual coil toroid at eighth H returning -39uA and next is single coil toroid at eighth H returning -27uA

This is a very informative video on magnetic transfer.

Thanks for  posting that video 
I had missed that one...

I was planning on making  one of those for  transfering power  back to source  from a bedini

I disagree  with one thing in the video   he says that to release the charge you you to remove the  bar  .........a coil wound around the bar and kept open until needed   should not interfear with the charging.

I was planning on  feeding  pulsed  from several  coils  around a bedini  into  a large coil like in the video

Then  have  one  bedini  coil  fed to the extra winding on the  top  bar.....this  winding  would have to  be in opposition to the  flow of the flux .......it should  disrupt  the flux just long enough to  pulse your source battery.
It would   be a low loss   pulse  battery ......
