Nathan Stubblefield Earth battery/Self Generating Induction Coil Replications

If you eliminate the wheel - well I believe I am at a loss, would the coil cycle itself?

Thats what Im thinking but its still speculation at the moment.

"to suggest the use of both directions of magnetic polarity in the core rod."

Havent studied that in depth. There are 2 magnetic fields at work here though. The Iron wire plus the iron core. Thats a magnetic field within a magnetic field. The iron field runs parallel to the current. The iron core field runs perpendicular to the current. Dont know if that has much effect on the coils operation.
  What im thinking is If the core itself reverses polarity then its because of the iron wire and how its terminated. If a positive copper was connected to one end of the iron wire or negative, then the polarity of the core is in that direction. The other end if connected would be reverse. If neither end of the iron wire is connected then the polarity is dictated by the pos copper or current direction and the iron wire just becomes another magnetic field and when its field collapses it creates a lower current back into the copper wire possibly in the reverse direction. Im seeing a polarity reversal if a pos or copper wire is connected to an end of one iron wire because of the flow of current in the iron wire. Those with working reed switch coils may know if they ran tests.

Ok seams your thinking of the primary (Iron/copper coil itself) and hooking to the Iron wire opposite end's to cause reversal.
haven't considered that. External input to the wire and from the ground batt. hum
This type thing needs to actually be done to observe how it will function. Good concept. If I understand what your suggesting.

Exactly. Yes its only the basic primary coil im talking about. The secondary can wait as its main function was to increase amperage.
This coil is really interesting for a variety of reasons. When placed into the ground its an electrostatic induction coil. Out of the ground its a hybrid induction coil. Experiments with standard interrupters and spark gaps could be made on the external standard induction type side. The spark gap intrigues me as a lower voltage spark gap has a more intense magnetic field than a high voltage. That magnetic field itself might be used to trigger another coil.

Got to this webpage http://ep.espacenet.com/numberSearch?locale=en_EP

And in the field Number: you type GB189807577 (then click on SEARCH).

May be this direct link works:

Greetings, Conrad

Got it.

Thank you,

@IotaYodi
Good info both. I will study this week after catching up on rest. Work is comming in and I need the funds for experimental stuff. :')
Are you aware of Cooks Electromagnetic battery Patent #119825 ? - 1871
So Ns might have been aware of it and used some of the info???
He uses two Double inductors once they are started he states they produce electricity on their own, once started. Until opened or shorted. Then need starting again
But he also states a rheostat can be used to drain some and leave a feeble current to build again.
Might NS's coil start itself in like manner. I beleave this is the type thing you refer to. Right?
His pat points out need for 4 coils. he also speaks to wire size, and hookup method.
Interesting info.

(Reason for mod of post)
sitting here looking at that Induction coil cutaway.png the spark is not being used but put Teslas ladder on top.
Ya know that Duel coil thing might not be that far off   (In my opinion)

(Modification again)
Put Cooks Pat and that Induction coil cutaway.png side by side and consider them. Now put NS coil for the primary, two of them in that set up.
I think thats similar to what your thinking. ?

Also it looks like pro built Induction coils use the iron wire for the core and is probably the way to go. I would think individually insulated with varnish, Bundled and Epoxied to make a core. Then for our purposes, the outside of the bundle should be sanded to expose the Iron and warped with cotton. This should minimize the eddie currents while producing better magnetic flux and allow the galvanic response.
