Stubblefield coils (bifilar) and speculations

Good News Folks
I just got permission

"There's no problem showing this to others. If you put it on the Internet or distribute it somehow, please credit Pogue Library, Murray State University.  RHL "
that is the author of the book Kentucky Farmer Invents Wireless Telephone, R H Lochte

I had to make screenshots then piece them in order. I added a prefix to the names so they should show up in order. Here goes:

@ Jeanna:

Fantastic!!  This was the book Maddog was trying to find.  I downloaded all the pages and will read on my surveillance job tonight.  Thank you!!!

Hi All,

I just received the brochure, well a copy.

I asked for permission to post it here. When if that comes in I will, but for now, I want to share this interesting info.

He has 2 sections electromagnet and induction coil.

In the electromagnet section he says if you hook up the "inner to outer or outer to inner" terminals you achieve the electromagnet.

So, this is where the reed switch or relay should go.

Later in the induction coil set up he says once you have achieved the electromagnet state and you add a secondary you will have the induction coil.

the first part is what I want to address. He is using inner and outer to solve the language problem. I think was it mthompson that described just this? NOT leaving the 10's alone but Connecting the 10Cu to the 6Fe / alternately the 10Fe with the 5Cu. I need to go back to look at the implications from yesterday's post.

Great find on the brochure! Can't wait to read!

In the electromagnet section he says if you hook up the "inner to outer or outer to inner" terminals you achieve the electromagnet.

So good to hear this. Exactly what I thought. Connect to the top or bottom of the battery which is another way to say the same thing. When they say inner to outer or outer to inner it confirms what (andy?) said about not canceling out the spin creating the electromagnet! Perfect! It's all confirmed and ready to experiment!! It functions just like I imagined and now it's just a matter of making the battery strong enough (big enough plates(wires)) for it to open the NC reed switch! Can't wait to get mine!!!

So just to be clear. The reed switch needs to be connected across one of the coppers and then the opposite of the bifilar to the iron. So copper to iron but important that it's from one end to the other or you will negate the electron spin creating the electromagnet!

Now,

Here is what happened when I tested connecting 1 inner with 1 outer and looked at the compass.

First, with the cell moist there is a voltage across any pair of cu and fe wires. In this case around 0.7vdc

Now, I test with a compass. near the center of the coil when there is still no connection the compass needle points mildly toward the cell.

As soon as I connect 1 inner cu with 1 outer fe the compass needle sslooowwwly goes to normal N. Now, this does make sense. When the cu and fe are connected all voltage goes to zero. It follows that the magnetism would also go to zero.

I may be turned around, but this says to me that NO is what we want.

Switch Open - current makes mag field.
mag field closes the switch connecting cu and fe wires
closed switch means voltage stops
no voltage - means no mag field-
no mag field means switch opens
