here is evostars new thread for his builds
http://overunity.com/17222/some-bifilar-coil-experiments/msg503934/#new
and his energetic thread

I hope this off topic reply gets removed with your off topic comment
But I see that tossing a line over to quotes from the other forum [MH] always causes these types of issues [tinder for a flame up.

I am glad evostars started another thread for his work ,perhaps he can get some feedback from people who are building and experimenting there ?

and Allen
I finally understand how it could take seven years to get a straight experiment from you on a claim 
I don't think its possible ....ever....?

for clarity I have never exchanged an email or a message with Aaron nor have I asked for you to be moderated here or even discussed you.[why would I ? we have never interacted ..
maybe one unanswered Question to you 5 -6 years ago ??

let experiments rule the day ,and hearsay stay in the wind ...not to be taken as fact
until proven otherwise.

Brutal honestly ,and no wooden Nickels.

I guess you figured out when Grum signs off for the night [moderator] and TinMan and magluvin have fulltime jobs ....

no I suppose you don't care..or respect much here anyway.

you just like fighting !!
seven years you say {with Tinsel and others] ??
never an experiment to define your claims in real time ?

I bet you could drag that out for ever...

Allen
some here who love this place and really try to do experiments actually like the  TOS agreement .
here >>>http://overunity.com/register/#.WO1N8Ll1roY
I am told it will be the guide for posting at this forum ?
and moderation will be by choice [your choice if you break the rules].

do you have a cause you feel passionate about an experiment you simply must share ?

please do

@ramset,

Stay off my back.

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

Really

Definition on googles first page at top
Quote: an electric current that reverses its direction many times a second at regular intervals, typically used in power supplies.

Quote wikipedia :Alternating current (AC), is an electric current which periodically reverses direction,

Quote sparkfun.com : Both AC and DC describe types of current flow in a circuit. In direct current (DC), the electric charge (current) only flows in one direction. Electric charge in alternating current (AC), on the other hand, changes direction periodically.

The list go's on.
So yes-some one has some learning to do !synchro!

Maybe we should change your name to !crash box!,as something is not meshing correctly there.

For nearly all models of induction cooktops, a cooking vessel must be made of, or contain, a ferromagnetic metal such as cast iron or some stainless steels. However, copper, glass, non magnetic stainless steels, and aluminum vessels can be used if placed on a ferromagnetic disk which functions as a conventional hotplate.  >>>

Are you sure about that MH  :o
Are you saying that eddy currents will not create heat in the highlighted metals?
All will heat,when held near a spinning rotor full of alternating permanent magnets.

Consider the case of the superconductor, where there are no resistive losses. The opposing flow induces an opposing field that is equal to the field of the approaching magnet, and so results in suspension, where the magnet floats over the superconductor, and in fact is "pinned" there even if the setup is inverted so it tries to fall away, but can't. 


Interesting  :D

So-what would happen if an ideal voltage was dropped across an ideal coil,that also had no resistive losses  ;D

Hi Brad,

I don't know if MileHigh is slightly confused on that or if he just worded it wrong.  But the induction cooker won't work with those metals only because it has a sensor that detects ferrous metals and will not turn on the coil until there is a ferrous metal near the coil.  When several of us were playing with them a few years ago we had to put some ferrous metal near the coil or bypass the sensing circuit in order to turn on the coil.

Have a good day or should I say night in your case.
