@Tinman,

What's the minus sign for on the analog amp meter (On the left)?

Show me an AC amp meter read a minus value.

If you have it set to DC amp's,and it reads a minus value,then you have the probes ass about.

@Tinman,

Please watch this video on "Electro-Magnetic Induction":

@Tinman,

Please watch this video on "Electro-Magnetic Induction":


https://www.youtube.com/watch?v=3HyORmBip-w

And that very video just showed you that current reverses direction,and dose not become some form of !negative! current.

What you are saying is this-when a car drives forward,it has positive motion,and when it drives backwards(reverses),it has negative motion. What in gods name is negative motion?.

That is okay but there is still a problem in your drawing, see it below.

Gyula
I find it strange the polarity changes but the n s polarity doesn't, i understand the current direction never changes.
I will do some testing.

.....polarity...negative... positive... right side up ...upside down...sideways...?
AC.. DC... Nosee..?

a better example would be to show a gain mechanism in any Direction ?

if you have Negative energy supplying gain ?
please post the circuit so I can replicate it ?

which video shows negative anomalous gain ??

please repost it ?

What we're dealing with here folks, is three people who never understood what alternating current is: Citfa, Tinman and ramset.

You are well aware you are not explaining your position
nor are you teaching the ignorant ?

yes I confess  I have no clue whatsoever what you are teaching here ?
that its light out when the sun is shining ? or dark at night ??

maybe I am a poor student ,you seem to revel in my ignorance ?

Please enlighten me/
with one example  which I can build ?

or keep this great anomaly a secret and keep taking peoples comments out of context
[since you refuse to offer a context]

have a good old time ,do you also pull the legs off of spiders in your spare time ?

the good news is my crystal ball is coming back from repair...

Pomodoro
yes the members love a flame war...
but not the members who experiment here...

@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?    8)

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