The bifilar pancake coil at its resonant frequency

[citfta]

Thanks for the clear explanation MH.  I have used your analogy of a coil and flywheel several times times since you first told me about it several years ago.  Most people understand that analogy better than the conventional explanation.  The only exception seems to be the ones that stubbornly stick to the idea that the current reverses when the coil discharges.  For some people there is no hope they will ever learn.

I outlined above and fully understand them and have a complete mastery of how a coil work

It would be great, because we all really need to understand it. The plain saying that it corresponds mechanical flywheel doesn't explain it very much - what rotates there? Note that large bifilar coil is merely symmetrical with respect to current flow in it. How the direction of rotation is defined for it after then? Why the zones pictured are formed along pancake coil? And has it something with overunity?

that stubbornly stick to the idea that the current reverses when the coil discharges

Normal coil "discharges" when the current is reversed (in similar way, like the capacitor - just the voltage/current phase is different). So, why the pancake coil should be an exception and when it gets discharged after then?

Hi Zephir,

If you really want to know what happens when a coil discharges here is a whole thread devoted to investigating that action.  There are some scope shots clearly showing what happens.

When the normal coil discharges, then the current travels in opposite way than during charging. I don't need to read whole thread about it, because it's commonly known situation. From this reason I'm just interested, why are you implying, that the pancake bifilar coil behaves differently.  Why the people shouldn't stick to the idea that the current reverses when the coil discharges?
