Free Energy will change the World - Free Energy will stop Climate Change - Free Energy will give us hope
and we will not surrender until free energy will be enabled all over the world, to power planes, cars, ships and trains.
Free energy will help the poor to become independent of needing expensive fuels.
So all in all Free energy will bring far more peace to the world than any other invention has already brought to the world.

Brovin shows in their experiments that the connection between the base and collector capacitance. On the basis of this effect, he made a motion sensor that reacts to changes in volume.

... if the secondary HV output winding has not controlled impedance at a maximum (say 30 or 50 watts - depends on your flyback) then you will definitely burn it out due to heavy loading the secondary by a large amperage (since in this configuration, primary draws as much power it needs till the secondary will have = l voltage source x 4 p-p x primary - secondary windings ratio or just to heavily saturate the inductor.

This is sound advice about protecting the secondary HV winding of the flyback transformer

So here are my questions for you, if you would be so kind to answer. (anyone else is welcome to jump in here also)
1. When wrapping wire around a piece of ferrite, would it be wise to address the formula mentioned above when trying to understand what is happening ?
No, because the magnetic flux density (B) is not constant throughout the crossection of the solenoid winding.
It is better to conceptualize these phenomena in terms of magnetic flux.

     2. Where does the extra magnetic field come from?
From the matter of the ferromagnetic or ferrimagnetic core.

     3. Could one construct a speaker that does not use ferrite or a magnet?
Yes.
Two air-core coils can attract/repel in the same manner as a coil and a magnet.
A magnetless speaker would have one coil simulating a permanent magnet. To accomplish this, the coil would have to have a constant DC current flowing through it.
An alternative embodiment of the magnetless speaker would have AC currents flowing through both coils.

         a. If so, then compare the energy it would need to produce the same sound from a similar ferrite/magnet constructed speaker?
By 'the same sound' I assume you mean the same sound pressure which is related to the force that the speaker's membrane exerts on the sound propagating medium. 
To simulate a permanent magnet, the energy needed to energize a superconducting coil is proportional to its inductance and the current flowing through it squared (LI^2).
A superconducting coil needs to be charged only once. A real coil needs to be constantly recharged because electrical resistance in it wastes/dissipates its energy as heat.  In any case the current needed to simulate a modern NdFeB magnet by a coil is on the order of 900000 ampturns/meter.  See the attachment

         b. Given that the energy is different, why?
Theoretically it is not different.  The energy in the magnet has been given to it by mother nature (but hidden by it too through domain randomization) and "unhidden" by the magnet factory where the magnet was permanently magnetized (unrandomized, ordered).
In a magnetless speaker, the energy in the superconducting coil simulating the magnet has to be delivered to it only once.  In a real coil the energy has to be constantly replenished as it is eaten up by resistive heating.

     4. In a conventional speaker, that has 3 exchangeable magnets of differing strength... Weak.. Medium.. and Strong,
         describe the intensity of sound from the same signal as you exchange the magnets.
Assuming constant AC current amplitude in the movable coil the force on the membrane will be weak, medium and strong, respectively.

         a. If different intensities... why?
This force does not depend on the magnetic flux density (B) but on the gradient of spatial magnetic flux density (dB/ds).

         b. Where does the extra energy come from?
Larger flux gradients are attainable with magnets having larger BHmax product.

So the electric field means nothing to you??? There is an electric field as well, weather it is easier to think in magnetics the electric field we have always shunned well except for a few of us.

So what if one coil was shorted and the other is used for the signal? Induction would act on the shorted coil much the same as a magnet would.

The energy in magnets are not given to them by mother nature unless they are natural magnets from the ground. A good majority of the magnets are nothing more then man made alignments. Again if magnets used heavy current magnetic fields then where is all this heavy current coming from??? I would say that a magnet is actually an electric field holder. The magnetic field is held up by this electric field and could not exist without it in the case of the magnet. We have to start to get this right and promoting older bs isn't gonna help. Magnetics has the same base rules as statics and statics are electric in nature. Although the magnetic rules do not conform to these rules They ride on top of the electric field that the magnet supplies. Viewing the videos on the picture of a double pair of magnets should show you what is going on. The lighter parts of the field are being excited by the high voltage they applied and so do not have any effect on the shape and form of the magnetic fields. The magnetic fields are surface fields and the electric are the supports for that magnetic fields. This causes river like flows in a spiraling  event around the magnets and separates the electric from magnetic fields. The clear rivers around the magnets are the magnetic fields themselves. They look just like the cymatic patterns and are just that.


It is interesting to view this in the Tesla method. It's a bifilar field effect and the magnetic field is one direction of the coil and the electric the other direction.
