Nathan Stubblefield Earth battery/Self Generating Induction Coil Replications

After jeanna reminded me about the Wiegand Effect:
http://www.overunity.com/index.php?topic=4455.msg212227#msg212227

I had to go back and beyond what I had to learn in the 80's regarding Wiegand wire
and it's applications. My case was security/sensor applications and I felt at the
time that it was to proprietary and I was allergic to licensing fees. So I kind of
took a pass on it but always stuck into one of those compartments in ones mind.

Here is a good background document on Wiegand wire and information about the inventor;
John Wiegand: http://www.defcon.org/images/defcon-17/dc-17-presentations/defcon-17-mike_davis_who_invented_the_proximity_card.pdf

Based on my limited exposure it doesn't matter how fast a magnetic field moves past
the cross-sectional area of the Wiegand wire. At some threshold a burst of magnetic
energy can be pickup up by a copper coil. The copper coil is wrapped around the
Wiegand wire and delivers a nice consistent pulse to a controller at which point the
magnetic field has to go in reverse polarity and cross the same threshold before the
the pulse is sent again. This time it's sent in the opposite polarity. This is the
Wiegand wire's hysteresis characteristics.

Here is John's Wiegand wire patent:
http://www.google.com/patents?id=TZMrAAAAEBAJ&printsec=abstract&zoom=4#v=onepage&q&f=false

Some, hopefully, short (for your sake and mine) notes may be of some interest.
Wiegand wire mostly consists of cobalt, vanadium and iron. Vicalloy is a tradename.
I think vanadium works in lattice structure forming alignments to the domain wall.
Beings how the Wiegand wire is composed, stretched, twisted, annealed, ....
the cross-sectional area ends up with a soft inner core (whose domains are naturally
aligned lengthwise) and a harder outer core (whose domains are naturally aligned
around the circumference helically (a 90 degree relationship). During the switching
the fields cross causing the effect; Barkhausen at the domain level or induction.
Never did get that nailed down.

From what I can comprehend it appears that speeds of about 200Khz to 2Mhz should be
able to be achieved and I think the higher speeds can provide the more efficient
symmetrical pulse generation. Stresses, length, temperature are some variables to
thresholds, frequency and the induced fields. For a tuned system to work properly
variables need to be controlled. Stable temperatures in the ground.


Perhaps one can now view the 1871 Cook patent in a different light as the Barkhausen
effect was briefly considered (I think by EMdevices and BEP) in the 'The Brnbrade
Coil/Overunity?' thread: http://www.overunity.com/index.php?topic=2630.0

Here is an old article on the inventor, John Wiegand, and his tech.
Popular Science, May 1979; 'Mr. Wiegand's Wonderfull Wires'
http://books.google.com/books?id=iwEAAAAAMBAJ&pg=PA102&lpg=PA102#v=onepage&q&f=false

It seems to me John liked to tinker with his pulse generator a lot; always working to
achieve higher output voltages. I think his highest voltage was 12 volts.
No mention of input power requirements or output power that I could find.
Kind of frustrating.

Pulse generator with shielded Wiegand wire: 4743780
http://www.google.com/patents/about?id=s8UzAAAAEBAJ&dq=4743780

Pulse generator with shaped magnetic field: 4484090
http://www.google.com/patents/about?id=qK4uAAAAEBAJ&dq=4484090

The higher the tension used when helically winding the coil around the core in the
smoothest way possible the higher the energy pulse. We start with a core made of soft
iron. Winding the core with high tension places uniform stresses in both the core
and iron wire. This should further define the domain wall orientation in the iron
making it more bipolar. Due to magnetorestriction the constantly present voltaic
effects, with the copper windings, and the resulting electromagnetic field will
either add to or subtract from the mechanical stresses.

Beside the size another potential benefit of the Stubblefield assembly versus Wiegand
wire is magnetic isolation. Magnetic isolation between the 90 degree relationships
could not have been as good in the Wiegand wire as compared to the Stubblefield
assembly. However, the magnetic gap between these relationships should be as small as
possible. Silk or thin cotton covering sounds good to me.

Take care.

@frozenwaterlab.
I have not seen Jeff cooks work but will check it out. Daniel McFarland Cooks I have. This is an old book from 1842. Lots of information in it. Kudos to Pese who gave us the link.

He scanned the whole thing and its well worth reading. Lots of devices shown. Its the only place I found on how to make a low voltage spark gap. If I make my Ns coil I want to experiment with spark gap magnetic fields and the radiant energy that comes off it.  Barlows revolving spur wheel or Ritchies revolving magnet are 2 of them. I would want to use something else rather than mercury though.  Barlow is in chapter 2 page 94. Ritchies is Chapter 2 page 100. Stubblefield himself may have read this book. The Induction of magnetism starts at Chapter 2 page 60.
The bundled iron wire core would be better. It just makes the construction a little more difficult but doable. Still the good solid iron cores are only giving folks milliamps. More galvanic and electrostatic action in the ground as well as radiant energy in my mind. Externally it still might be used. Who knows it might even work in a solution of water and iron oxide.

The Ns coil should be pursued just because its not fully understood. Once it is totally understood it may lead to other discoveries.

I tried to browse the cook.htm book from the link and it only show an empty page.

Has you or anybody downloaded it to a place we can browse or download it?

Jesus it only appears that way. Use the arrows on the right of the page to scroll. To download it click on print and it gives instructions. I would download it. Lots of excellent material in it.

Thank you that was what I did.
