The bifilar pancake coil at its resonant frequency

[tinman]

@Tinman,

Which way does current flow in a Ruhmkopff Secondary Coil when the current's interrupted in the primary

Are you talking about the ignition coil?-which was not invented by Ruhmkopff,but by Nicholas Callan in 1836.

First off,from what i have read,it seems as though we are talking about interrupting the current flow through a single coil/inductor,in which case,the voltage will invert across the coil/inductoor,but the current will continue to flow in the same direction.
If you are talking about an ignition coil,then the same applies with the secondary-only the end of the secondary is joined to the start of the primary-->remember,with an ignition coil,where points were used,it was the ground side of the primary that was switched via the points,and not the positive side of the primary. The end of the secondary was joined to the start of the primary(the positive end),and then the start of the secondary became the end in which the current flowed from,as that would be sent to the positive side of the spark plugs via the distributor.
So the ground(negative)was your engine block,and the sparkplug leads were your positive side.
So,as you can see,the current still flowed in the same direction through the secondary, when the points opened,and broke the current flow into the primary.

and can you define "Negative Current"?

The flow of current has no polarity-it has direction.
Voltage has polarity.

Hi @Tinman,  I know that overunity people are all liberals by their very nature - but as a moderator you should move all off-topic comments into their corresponding threads - not to feed them with their discussion in their original thread

You will find that nearly all threads here on OU.com,have !off topic!! conversation within them.
There is no way i have the time to be moving all off topic comments into other threads.
Some off topic conversations lead to people being taught things they never new-like the current flow through a coil,when the source current is interrupted.

The question of current after interruption of coil is theoretical question of CLASSICAL physics.

And there you go-a classic example.
It is not theoretical at all--it is fact,that the current will continue to flow in the same direction through the coil,when the source current is interrupted/disconnected .

The overunity forums are losing their original drive and they get flooded with ignorant pathoskeptics

Who are these !pathoskeptics! you speak of?-->those that correct others mistakes perhaps?.

today most of progress actually comes from private researchers and the classical overunity forums are just watching this development in silent surprise.

Could you point us in the direction of one of these !private! researchers that have achieved OU ?.

This is because the free hoarded community is maybe creative and inventive, but it remains undisciplined and lazy enough for implementation of its own ideas. What I'm missing here is streamlined brainstorming of experts leading to proposal and testing of particular circuits. The clueless senior twaddling is indeed mentally comfortable - but it leads nowhere.

There are many here that will build and test any circuit,that has a claim of OU behind it-including myself.
But what we have found is,when those that replicate claimed OU circuits,and are skilled in the art of EE and accurate measurement protocols,come up with under unity results,the claimant of the OU device simply say that we dont know what were doing-or we made errors in measurements.

For those, who want to ask me a question, Personal message me. Dont do it via these posts. It will drown, and i won't see/read it.

The pathoskeptic is everyone who for example says, that overunity doesn't exist, because he never observed it during his tinkering (like @TinselKoala is saying) or that overunity doesn't exist, because it would be utilized already and awarded with Nobel prizes (@MileHigh and others). Such a nonsenses shouldn't be tolerated here...

From perspective of mainstream physicists whole the overunity subject is also mistake and they oppose it wildly, so that the usage of "mistake" word is subjective trolling too.
Once the bifilar coil exhibits self-capacitance, then its current after interruption may evolve differently, because it can behave like the capacitor too.
The idealized assumptions of mainstream physics trolls therefore will not apply here and only experiments can determine, what we will observe there.

My question is, if it's possible to create discussion thread, where I could delete/hide all off-topic and trolls posts (including those of other moderators) according to my own opinion and to keep the subject coherent in this way?
You can set up this thread in this way for example instead of creating a solely new one.

You need to get your facts straight, Zephir, if you are going to be mentioning me or MH in your posts.

And you need to provide some evidence of your own for the outrageous claims you continue to make, while you dodge and weave without admitting the times you have been soundly refuted. You have _never_ posted a single demonstration or experiment of your own... and I know why: You cannot.

Explain the LED flashes in my Coil Current Demonstration (2) if you believe that current reverses when the power to a coil is interrupted. Why are flyback diodes often placed across inductors that are pulsed, and in which direction does the current flow through those diodes? How many times has this challenge been made to you now, without any response?  You know by now that you are wrong and that is why you avoid trying to answer. Admit it!

where I could delete/hide all off-topic and trolls posts (including those of other moderators) according to my own opinion

But didn't you say that this wasn't the place for opinions? Make up your hypocritical mind, why don't you?  If you want to be the censor, move to some other forum, like EF. I'm sure we will be happy to see you force your "opinions" on others over there.
