Nathan Stubblefield Earth battery/Self Generating Induction Coil Replications

Hi All,

I have been looking for a supplier of bare copper wire in A and I think I found one called TYCAN in Mittagong in New South Wales, if anyone wants to take a gander, look here  http://www.tyree.com.au/tycan-australia.html 

Sorry, this turned into a dead end, they stopped making bare copper wire 2 years ago, but if you go here http://www.tycab.com.au/index.php?option=com_content&view=article&id=120&Itemid=106 then you can see what shiny copper runs are like.


I don't know if they have a range of cotton insulation, but so far it dosent look likely.
I will ring them shortly and get back with more info on this.
EDIT been in touch with them, no they don't sell cotton covered copper wire, shucks.


Annealing Copper wire, or making it softer to use, I found a few good hints here http://cs.artjewelrymag.com/artcs/forums/p/7407/35343.aspx

They explain it in simple english, something I understand, lol.

Here is a site that sells cotton tape in various lengths and widths if one wanted to cover bare copper wire.

Jim:

Good to see you here.  I hope you are well.  Lasersaber's source seems to be pretty good in that it is cotton covered wire with no enamel or other insulation on it.

I hope to be able to acquire some one of these days.

Good to see you again Mate.

What I meant by "doesn't work well" is that there is no perceptible magnetic field generated when any of the wires are connected in any fashion. I attributed this to the glass covered wire, but that's probably not correct...too many other possibilities, one of which is all the rust on the iron wire I had at hand...didn't think it would matter, so I didn't clean it off.

I made a very simple winding jig to make the job easier. I'll post photos of it soon.

I came up with a mathematical formula for estimating the amount of wire needed for any given coil. This gives the total number of inches (Fe and Cu), so of course, divide the result by two to get the number of inches per wire. I'm also working on an Excel spreadsheet and will post that when finished.

Before I constructed any of my NS coils I used a magnet to determine the iron content of the core.  Now, as often happens, I learned that soft iron means that it will not hold a magnetic field, which is exactly what we look for in toroids in the JT topic.

This is why I now think that a core of ferrite will work even better than anything NS had at that time.  The core needs to magnetize when energized but then quickly drop it to get the benefit of the spike.  We on the JT topic know this is correct with our experiments over there.

I am looking for a ferrite core for my next NS coil.

@ Bill,

Thank you for the kind words.

Well, I gone and done it, made my stubblefield coil at loooooong last.
Theres 10 Layers of windings, consisting of 76 bifilar turns per layer.
So I gues there is 760 turns in total.
I didn't use any cotton covered copper wire.

Copper wire is just enameled copper wire, BUT I also used a plastic covered iron wire.

Anyway, it does react to body capacitance, but a funny thing happens with it.
I notice the MV builds up, then sometimes it reverses polarity.
Havent a clue whats hapenning here.
But I can hold a neo close to it and I can feel the neo vibrating ever so slightly

Below is my pride and joy lol.
