Stubblefield coils (bifilar) and speculations

[jeanna]

Thanks,

I will get the switches.

The thing I want to say is that if you actually do not connect the primary wires you get the voltage. It comes from the moistening of the cloth and the ensuing galvanic reaction creates the voltage. As soon as you connect the other terminals, the ones that have the meter on them will read zero.

He (NS) goes on to say that when the leads 5 &6 are connected, they will produce the magnet as long as the coil body 4 is moist. It becomes a self inducing electromagnet. So, the electromagnet part happens when the voltage reading has gone to zero. I assume that this is the electrolysis part, the part where the iron and copper get replated onto the wires.

So, normally open would give the current/voltage and when closed will close off the current or voltage and establish the magnetism.

Is this right?

My confusion comes about with his sentence that it becomes a self generating electromagnet when the terminals 5.6 are connected because of the current going through them. Since, by connecting 5.6 the current stops.


I will look for those switches. I don't remember seeing leads.

Thank you

I see the ends are leads on 2 of them

@Jeanna,

Maybe you are getting a voltage buy using a test meter but isn't that creating a closed circuit in itself which is why you are seeing the voltage? I think the secret to this make and break action is talked about in 75-85 in his patent.

NS says in his patent:

IT WILL BE OBVIOUS THAT BY REASON OF THE MAGNETIC INDUCTIVE PROPERTIES OF THE COIL-BODY 4 THE CORE-PIECE 1 WILL NECESSARILY BE MAGETIZED WHILE A CURRENT IS GOING THROUGH THE BODY 4, SO THAT THE BATTERY MAY BE USED AS A SELF-GENERATING ELECTROMAGNET, IS FO DESIRED, IT BEING OBSERVED THAT TO SECURE THIS RESULT IS SIMPLY REQUIRED CONNECTING THE EXTENDED TERMINALS OF THE WIRES 5 AND 6 TOGETHER?

So the normally closed reed switch should be connected to terminals 5 and 6!

The key to this primary is that it's a SELF generating electromagnet and we can use the electromagnet to activate the reed switch thus that opens the reed switch (circuit) which stops the electromagnet which then causes the reed switch to close which then repeats the process over and over. I'm guessing the frequency of this will be relative to the amount of windings on the primary.

I would not be so concerned with the meter reading because where you put the meter (what leads are you connecting it to) might cause the circuit to start up. I think either watching the action of the reed switch or putting a secondary winding around the primary and test from the secondary so you are isolated from the primary.

If it's not clear I can draw it but lets see if I can explain it. From the patent NS said that 2 of the wires from the primary, when you connect them, start the voltage in the primary. This I assume would then create an electromagnet in the bolt. So take those 2 wires that he says to connect (make and break) and put one on one lead of the reed switch and the other wire on the other end of the reed switch. The reed switch would have to be a normally closed type so that when it was connected it would immediately cause the magnetic field to start in the bolt which would then open the reed switch which would turn off the magnetic field and then the reed switch would close (it's normal state) and repeat the cycle over and over. The speed would probably be determined by the amount of windings on the primary which would effect the speed the magnetic field collapses.

The reed switch probably should be as close as possible to the bolt since I guess it's a week magnetic field. These reed switches are very sensitive so should be able to be activated with very little magnetic field.

If it's not clear enough I can draw it.

I am not  sure that the coils  that we have made create enough  magnetic field to  affect a reed switch

@ Gary:

They should have enough field to attract a thin one.

@Gary

Yes that is a big IF in my head also, especially since I haven't even started to make one of these but in his patent he clearly calls it a self generating electromagnet when 5 and 6 are connected. When I read the patent that is the part that lights up for me! It seems the key to the device.

Well hopefully someone can test these with a very sensitive normally closed reed switch, placing it as close as possible to the top of the bolt or wherever the field would be the strongest.
