Hi,  Im a first time poster Im a newcomer to all of this.  Independently I began researching stubblefield and consequently his earth battery and voila! I found you guys.

I have been following lasersaber and jeannacav's vids on youtube and read through the tons of posts on the subject of the self-exciting induction coil and I think I have figured out something about it.

I was reading a section on transformers in this electrical coursebook but before they delved into transformers they had a brief section on induction coils. 

Induction coils work by interrupting a steady dc current, via a mechanical switch ( the reed switch in the case of lasersaber's coil )  or transistor.  At each switch, a emf is induced in the secondary winding,  but only at the opening and closing, hence the need for a core of high permeability and low retentivity.   The steady supply of dc is coming for the galvanic action of the bifilar coil in electrolyte medium.  Though there needs to be reaction to generate current, like more common earth batteries it is found that a greater difference in moisture content enhances the output of the galvanic cell. Hence the fact it works BETTER while drying out.   Strength of the battery would also fluctuate with ground resistivity and other factors like diurnal movement, placement in respect to magnetic declination,  north-south orientation  etc.

One thing of note that I believe will greatly help all of us in our Stubblefield studies is something that was said in that book i was reading.  ( The reason why i brought the book up in the first place )   Instead of shorting the wires to create the electromagnet,  the time between flux changes can greatly decrease if a capacitor is connected there instead, it will gather excess current slowing down core saturation and will provide greater induced voltage in the secondary by decreasing the time between "switches".

So what do you think?  Im not sure if i have a handle on all of this, so any input regarding to my suggestion and/or  my idea of how the battery/self-exciting induction coil works  is greatly appreciated.  Hope to hear back from you all soon! 

@ alchemist123,
Firstly let me welcome you to the forum (the blister club), nice to have another new chum here   

It's good to know you have been studying up on what we are all trying to do here.

All the points you have raised are worthy and will be studdied closely no doubt.

About the drying out effect, I have noticed this from those who have tested their coils, plunging them into a bucket of water they will work until the coils are saturated, then the electrical effect drops, then as the coil dries out it begins to recover it's output until it passes a certain point then falls.
Lasersaber has noted this effect.
If the coil was placed in the earth (which is damp) seems to allow the coil to "tune" the dampness within itself, retaining a certain amount of moisture seems to allow it to operate.

Pirate88179 has studdied the angles of rods in the earth, which will enhance the output of his earth cells, which I'm sure can be applied with stubblefield cells also.

The trick would be to find a happy medium so it would operate continuously.

"As the magnetization force increases ( or the current over the conductor is increased), a point is reached where the magnetic material or core will saturate. See point "S" above on the curves. When that happens, any further increase in H, will not increase the flux. More importantly, the permeability goes to zero as the slope now is flat. In this situation the magnetic material or core will fail to work as a transformer, chokes, or inductors.

So, it is very important in a choke or inductor design, not to drive the core into saturation by increasing the current (AC or DC). Usually it is the DC current that saturate the cores since it is a constant current, and puts the cores to a certain flux level."

So Im thinking the switch may need to open/shut before the saturation point. Number of turns,core materiel,voltage etc will determine the switching rate. Most think this is a radiant energy or cold electricity device. The voltage and current relationships as far as ohms law goes with radiant energy doesnt seem to be known. The more current though the more radiant energy.

My wife broke a food chopper. I took the laminated core out and tested it. Absolutely no remanence. Plus it magnified the field intensity of my toroid magnets substantially.  I wonder if they make them in round or rectangular rod configurations.

That is a very cool experience.
Do you think there was ever any cotton insulation on the copper?
Was it varnished copper like jim's?

Not in mine, but yes on stubblefield's, and definitely on stephen vail's one, in order to sustain a galvanic like reaction ala alessandro volta whom used copper and silver coins separated with carboard soaked in salt water,but this coil doesn't depend on the galvanic but the radiant/cosmic energy absortion through pulses and in the ground also take advantage of the telluric currents
What I have been not asking very well is 'how well can a thing like this work if I have only a 3/32 inch diameter welding rod as a core?'

Eveything is proportional, core thickness and length, wire windings and diameter of it,so it will work with the right calculations, to avoid hysteresis loses making a core with several of this wires will act as the E insulted laminates of a regular transformer making more efficient with less losses eddy currents etc  

Hope this helps Jeanna

intresting you mention that ...   

i built an electrode core some time ago .. useing zinc coated wire thin  many in a bundle then wrapped them with 1   of the same ... 

cheep way to make zinc rods ..  of any size ...  i would expect results from the way it is made alone ...

; )

@Mk1   since this Stubblefield coil is very similar to an ignition coil Id say its a pretty good bet.

@electricme    The drying out effect I think can be simply explained.  Think about a battery,  a primary cell works because an electrolyte is acting on ONE of the electrodes.  I think this is where we are seeing the discrepancies (spelling?)   in the experimental results furnished by the people of this forum.  As you said,  until the coil-body is saturated it works, and as it dries out (up to a point it works ). 

Copper and Iron are electropotentially different, so no matter what a feeble voltage can be "drawn" just by connecting them. 

In the patent, only the copper wire is expressly said to be insulated the iron wire is not, though it can be without ruining the function of the device but limiting it in ways expressed by Stubblefield.    When the coil is fully wet, the electrolyte is acting on both electrodes equally, so only the electropotential difference of the metals is affecting the amount of voltage.  As it dries out, there is a difference in the amount electrolyte acting on each electrode.   So when soaking and when drying it seems to work efficiently.   

I think this is why Stubblefield reccomends this be buried in moist earth,   What is necessary is to aid the voltage differential between electrodes.   Increase in voltage through the winding increases current ( ie Ohms law )  hence greater electromagnetic effect and greater effect on the secondary output.

For an above ground Stubblefield coil, it shouldnt be too hard to figure a way to keep it moist,  but for "freeenergy" use  i say the earth is the way to go, you can connect these by cells and utilize difference in locational voltage potentials to power a primary induction coil/battery. 

@ IotaYodi   I agree the core composition is vital.  Soft magnetic materials are needed for low retentivity(remnance),  good places to find these are transformers, as the function of a transformer relies entirely on this concept as well.  Losses due to eddy currents can be reduced by either using a high resistance ferromagnetic material or using many smaller pieces to comprise up a core.   I think that a bundle of iron rods may fare better than the single bolt in the original stubblefield design.    Or better yet Permalloy rods.   Mu-metal i have read has a lower saturation point though is comparable to other alloy cores,  however it is alot easier to work with. Shouldnt matter though for this invention.
