Where the OVERUNITY using INDUCTION COILS comes from (eg Joule Thief)

[norman6538]

Current has a time factor so 20k cycles makes a lot of flux changes but
the  current has a time consideration.

I always liked Don Smith's "watt second" for a current measurement.
But somehow he advocated that the extra power came from the high cycles.
I never got that.

So using 1 watt to power a 60 cycle oscillator we do not get
60 watts out - we get  1 watt but only for 1/60 second but for 60 cycles.

...the high frequency switching (on and off) in the tank circuit of the joule thief is enough to get more output energy than the energy put in.

The Joule Thief is essentially a boost converter.
It steps up voltage at the cost of current.
It does not step up energy regardless of the switching frequency.

The key is movement of flux lines across coils.  That's where I believe the real current is.

The "movement of flux lines across coils" is commonly denoted as ΔΦ (a change of flux penetrating a coil).  The speed of that change (or "rate of change") is commonly denoted as dΦ/dt.

The voltage induced across an open coil depends on dΦ/dt but the current induced in a closed ideal coil does not depend on dΦ/dt.

The faster you move the flux lines, the more the rate of charge is flowing.

"Rate of charge" is not a valid phrase for communication.  Did you mean the "charge's rate of change" or "charge per time"?
If yes, then Coulombs per Second are simply Amperes - a measure of electric current.

In any case, the current induced in a closed ideal coil does not depend on dΦ/dt, it depends only on ΔΦ.

This is what I'm trying to get across.
The high cycles means that the movement of flux lines (expanding and collapsing) is faster.

Do you not get more current if you move a magnet across a coil faster?
If I were to spin a generator twice as fast, wouldn't I get twice the current?

you are close but sill far far from overunity
ok, fine here it is
verpies is 100% correct - it's the amount of flux what matters
or rather how to move it without paying like having a free lunch 
or rather which flux
or both
it depends
in one case frequency is important like Don Smith said
in other case flux is more important like Figuera said

I'm starting to talk like Tito did, but I'm not Tito
you will know the answer
it's easy

or HOW
