The bifilar pancake coil at its resonant frequency

[synchro1]

@ramset,

Here's a cool project for an electric buzzer. Joseph Henry, of the unit of inductance (Henry), patented this spark gap generator, and it can be turned into a wireless telegraph with the simple addition of a contact key. It generates AC current:

Not all of us have endless hours to torture the ignorant ...
or gloat in some self enlightened grandiose moment !!

so you are saying this negative gain mechanism [extra energy inters the system thru
the negative resistance ?
am I even saying that right ??

please clarify if not ...

this can be found in this Vid you posted after my question on a negative gain mechanism [excess energy /anomaly / whatsit..?
is this what you call negative resistance ??

this is a gain mechanism ?

if you are done speaking in tongues and sentence hatchet quotations
maybe you should just give this man his thread back?

this
http://www.energeticforum.com/renewable-energy/20714-magnetic-field-bifilar-pancake-coil-2.html

is a much more interesting path than your half measures....
a solid state spinning event happening over pancake coils ..

maybe you should start your own Scrapyard magnet secrets thread ?
you could probably milk it for a few years...

evostars started on a much more interesting thesis with  pancake coils [solid state]
ala TPU perhaps

let him have his thread back
while he has told you he finds your work interesting
its not his path...
please respect his request here...many are intrigued by evostars work

Dear All.

Let's put a bit of perspective back....

This is the scale of the Pancake coil !!

Cheers Graham.

Dear evostars.

Is that one of R M Cybernetics PWM's you're using ?

Grum, thanks for posting that nice large famous photo of St. Nick sitting next to his big flat coil.

The scale of the photo makes it easy to trace the turns outward from the center.

So is it bifilar, or not?   

For those with weak eyes, here's a blowup of the center of the coil. Bifilar.... or not?
