Quantum Energy Generator (QEG) Open Sourced (by HopeGirl)

[Groundloop]

Let me rephrase your question then:  "Given two tank circuits, one using larger toriods than the other, which circuit stores more energy?"  The answer is:  "There is not enough information supplied to answer the question."  A bigger form can store more energy before it saturates than a smaller toroid.  As you change the dimensions of the toroid the inductance per turn changes as does the resistance per turn.  The ratio of the inductive reactance to the resistance at the resonant frequency determines hat fraction of stored energy is lost each cycle, IE it determines the Q factor.  The inductance and the peak current determine the peak stored energy.

Mark,

It IS a very simple question, there is just one coil with a ferrite core and one capacitor in parallel with the coil.

First we connect an oscillator to the L/C tank circuit and store some energy into the tank circuit, then
we disconnect the oscillator. At the same time we increase the Ferrite core to double size and connect
the tank circuit to a load to measure the output. Will the output be higher or lower than the energy inputted
into the tank circuit when we increase the size of the ferrite core?

I do not think I can explain it simpler than this.

Groundloop:

I usually find simple examples like that fun.  There is a limitation or perhaps we can call it a flaw in the logic of your example.  However, I would prefer to discuss that later.

Permit me to give you a very simple and related example.  Just like in your example, we will assume everything is based on idealized components (zero wire resistance, etc.)  I think my example will give you some insight into your example.

You have two coils in series, Coil A and Coil B.  The "left side" of Coil A connects to the "right side" of Coil B to form a  circuit.  In other words, the current flows through Coil A, then through Coil B, and then back to Coil A.  There is no magnetic coupling at all between Coil A and Coil B.

When you start the experiment there is a zero-ohm jumper across Coil B, effectively taking it out of the circuit.  There is no current flowing through Coil B at the start of the experiment.

To start the experiment, by "magic" you have one ampere of current flowing through the circuit.   So that means there is one amp flowing through Coil A, and Coil B is being bypassed because of the zero-ohm jumper.

Now since this is an idealized example, if you do not disturb the circuit, current will flow through Coil A forever.

So the question is, what happens when you remove the shorting jumper across Coil B so that it becomes part of the circuit?

(MarkE and other regulars who know please don't answer.)

Mile,

I have a question for you, what happen to the stored energy in a not connected L/C tank circuit if you double
the core size after you have charged the tank circuit?

Might be wrong but studying magneto restrictive materials along with basic understanding of why magnetism manifests IE organization of domains(which costs energy) plus the realization that what you are asking is actually impossible(" Let us assume we add that core material very fast and at no energy usage to do so") might help you come to a conclusion.

>>that what you are asking is actually impossible

This is only a thought experiment and it is not impossible to increase you core size in a thought experiment.

Ok then sure its possible if things could manifest out of the abstract into concrete reality unimpinged upon by the laws of physics. Thats a really useful thought experiment.

I will give you a simple answer.  I will assume that the core is not saturated in all cases.  I will assume that the dimensions of the coil do not change.  The permeability of the core affects the inductance of the coil as "seen" by the coil.   If you add more core material, then the permeability of the core will not really change, as "seen" by the coil.

So the simple answer is nothing changes.

If you think of the core as a "tank" to sore energy then think if this:   You have a 5-liter tank that is filled with two liters of water.  Now you change to a 10-liter tank, but it still is filled with two liters of water.   Nothing has really changed.

The water represents the stored energy in the (coil + core) combination.
