@Zeitmaschine OK fine. I have one doubt whether your assumption may applicable in Tk's Aquarium device because it is totally insulated....

Suggestion to electrically disable a Faraday Cage

»You can't disable a cage, but you might be able to make a switchable "leak" in the cage.

You might need to do some fancy shielding around the hole and switch, to prevent leakage when the switch is off.«

Hmmm ....

Is that shielding around the hole fancy enough?

@Zeit,I think it is just a soldered tag and nothing special, also the copper box does not leave much room in side itself due to the row of either transistors or diodes circling the lower half, which also have to be wired up I guess inside. The switch that is flicked to get spark going is the other side just out of your picture.

one side or opening from the faraday box is a ferrite that is your valve.

Wesley:
(as magnetic field and any current is associated with electric one (creating electromagnetic one), at 90 degrees both are inseparable in energy transfer).


Note:
( steady state magnets are used to accelerate electrons in  accelerators...... do they give out any energy  at all- no they not.?)

or
ferrite rod inside box


or


Tesla coil with rod inside, 
what is the sides of coil? metal? cage?


so what that you have opening from up and down.


electrostatic field does shielding.


Well with  faraday box it would be better as less energy needed to open the valve.

In a (completely closed) Faraday cage there is no electric field. The Earth's electric field surrounds that cage but it isn't inside that cage. The cage is empty.

1) Now we open that cage (by removing its walls).
2) The Earth's electric field can now flow into the space of that former cage.
3) We close that cage so again there is no electric field inside.

Question: Where did the electric field go that was in the space of that cage while the cage was open?
Answer: It was converted into an electric current (going to the ground) when the cage was closed.

Therefore, if we have a Faraday cage and we open and close it in rapid succession (high frequency) then we should be able to generate a continuous ground current of noticeable magnitude. So -as I see this- simply closing and opening a Faraday cage will convert the electric field (of the Earth) to an electric current which can be used to drive a load.

Thus the next question: How to open and close a Faraday cage automatically without using a lot of energy in order to do this?

Hmmm ....

Use a rotary Tesla switch.
Cost of switch:- 2 aa batteries.
Switching ability: hundreds of killowatts.
Cost of manufacture: 1 pound from the pound shop or 1 dollar from the dollar shop.
(Plus the Faraday cage)

The Ferrite Anomaly Solved.
 
 

Electron activity constitutes circular charge flow around the coil;  this generates an alternating electro-magnetic field within the ferrite rod;  which subsequently energises and aligns the unpaired electron spin gyros within the ferrite.  Hence a ferrite does no more than concentrate the alternating magnetic field, as generated by photon induced electron flow within the coil, into aligned electron spins within the ferrite, and via its concentrating permeability, 'Q' magnifies the voltage transduced by the coil with an improved circuit efficiency through phase shifted oscillation of resonant energy exchange
 
Ferrites are not magnetised by any magnetic component of electromagnetic radiation, and the coil is the only provider of external alternating magnetic field lines entering the ferrite. And thus inducing an electron spin coupling within the ferrite, then the electron spin alignments within the ferrite.
 
When a coil is wound over a ferrite it does not matter whether that winding is electrically energised by a radio-frequency signal generator or via electromagnetic radiation;  either way there will exist an associated alternation of magnetic field lines entering the ferrite. 
 
We can imagine half toroidal (doughnut like) shaped field lines coming up from outside of the coil winding, rolling over the coil end and linking into the end of the ferrite rod.  As before these coil induced magnetic field lines must generate related electron spins around them within the ferrite, these being concentrated where the external field lines turn around to enter the end of the rod just inside of the edge of the coil.  Now at the end of a rod these coil induced electron-spins within the ferrite are axial, and hence electrons possess the same direction of angular rotation as those within the ferrite just inside of the coil winding, however, they are all alternating at radio-frequency, and have greatest intensity and alignment closest to the wire coil turns.
 
Thus any magnetically induced alternating electron spins at the outside edge ends of a ferrite rod cored inductor, cannot fail but to parasitically induce a 'Q' reducing central vortex of counter directional electron spin interference from the end, and into, the centre axis of the rod within the winding.
 
Hence any ferrite rod physically 'too long' with respect to the desired frequency of operation or the length of resonant coil wound upon it, simply cannot homogeneously develop co-axial electron spins (magnetic domains).
 
Also any 'too thick' a ferrite rod will parasitically energise its own axial end interference vortex zones due to centre electron orbits becoming spin reversed and increasingly lossy with increasing frequency with respect to those which are more strongly energised and aligned by the alternating electromagnetic field lines entering the rod around the outer end and edge much closer to the field generated by coil winding itself.
 
(1) at medium/high frequencies do not use a ferrite core very much longer than the coil overwind itself;
(2) obviate the development of an energy sapping axial interference vortex by using a hollow ferrite;
(3) wind a larger diameter of tuned coil in order to increase the alignments of photon transduction activated electron orbits within the hollow ferrite.
A 100mm long ferrite core Inductor having a much larger diameter and longer coil than is usual in order to increase field/ photon transduction.   
 
The spin precessing are like little gyroscopes due to resonantly alternating energy oscillating between the charge on the tuning capacitor plates acting upon electron motion, and thus their orbital alignment, via the tuned winding induced alternating magnetic field, such that that magnetic field (acting just like gravitity does upon the spinning mass of a gyroscope) attempts to topple electron orbit spins within the ferrite, first one way and then the other.  Thus I could imagine the axes of electrons spin precessing within the ferrite sleeve instead of linearly oscillating like a pendulum would though zero, with the electron orbits gyroscopically storing plus returning more energy, and that gyroscopic electron orbit precession possibly becoming an alternating magnetic wave, which could explain the very high degree of resonant field amplification quite literally generated around these ferrite hollow cores…
 
After reading these pages above and realising (or experiencing via construction as so many people already are) what it is we have all been cheated out of for so long, you might better understand my stated disdain.
 
There are no 'transverse magnetic-voltage field' components associated with the propagation of electromagnetic radiation, and magnetic fields are the result of electron motion;  also magnets or materials rendered magnetic via magnetic field lines passing through them, as may be induced by electron flow though a coil overwind, are concentrations of aligned atomic sized electron spin orbits, which when acting in the same sense throughout a body of magnetised material are effectively - electron gyroscopes.
 
For I believe the certificated 'Professionals' have been wilfully duplicitous, and won't come clean until we point out that keeping the real theories as if 'Official Secrets' and thus away from those of us who pay their wages and pensions, is both dishonest and disrespectful of the whole of humanity.  What is so difficult about speaking the Truth?

Hi Zeitmaschine! Where did you get that schematic from?
THX in advance!

And fish cannot feel earthquake under the water.
Maybe it is that one:
