Canceling Lenz's Law - Methods

[zuvrick]

I agree that we appear to be using different definitions of "handedness". I look at the coils or spirals as they turn outward from the center, and that is what I saw as right- or left-handedness, i.e., clockwise or anti-clockwise direction. Intuitively I would find the left figure where the wire keeps going in the same direction to be correct, but it was observed to violate my definition of same-handedness. So ambiguity can exist in the definition. Thanks for your observation and comments.

You are welcome.
You must imagine yourself travelling along the wire like an electron. If you take your right hand and call it the electron, point your thumb along the wire in the direction of travel (or actually in the "conventional" current direction, backwards) then your fingers will "curl" in the direction of the magnetic field induced by the motion of the electron.  If you then compare the two coil drawings you will see just where the change in handedness occurs-- in the righthand drawing, the first outwardgoing spiral makes a field that comes "out" of the center, whereas the second ingoing spiral makes a field that goes "in" to the center (or vice versa, I get confused too). The second arrangement will actually result in cancelling fields and small inductance -- it is effectively a "hairpin" style bifilar winding -- , whereas the first will result in reinforcing fields and larger inductance. There is yet another way to do it and that is to take the outer end and not wind but just bring it to the center straight, and then continue winding outwards in the same direction as the previous layer. This is closer to a Tesla bifilar winding, but in adjacent layers instead of in the same layer.

I hope I've got this right... it's been a long day and it's very hot in here, my brain is fried! Corrections welcome....

Hi All,

This patent application looks like it has potential:

http://www.google.com/patents/US20100194227

"A power generator produces electromotive forces in the same direction on all windings to prevent lowering of rotational forces of rotor plates due to magnetic fields."

Looks like a sideways Gramme ring with switching circuit to cut or reduce the C-EMF.

Hi all.

I've been reading your posts and I have a question.
I am attaching a file, that shows a coil and 3 magnet positions (A, B and C). A is when the magnet approches the coil, B is when the magnet is parallel to the coil and C is when the magnet leaves the coil.

As far as I understand the Lenz law, the induction creates two magnetic fields, one when the magnet approaches the coil (and builds up as the magnet gets closer and closer to the coil) repeling the incomming magnet, and one when the magnet is leaving the coil, where the coil tries to hold back the magnet from leaving.

I've seen that under load my rotor comes to a complete stop due to Lenz law. I've been experimenting a bit and I was just curious to know if I could build a circuit that disconnects the coil right after position B, or maybe just before.

Electronics is not my strong side, so I do this for hobby only. Therefore I wonder, whether this even would make any difference? In my mind this would reduce Lenz by 50% as the second Lenz magnetic field would be zero (at least I think).

I've tried to do something with a transistor that gets the base current from the Bedini circuit, and it seems to slow down the rotor, but not completely stop it. Therefore I am hoping that someone can show me a circiut diagram or something that I might try to experiment with.

Hi zogorean,

Have you considered:  when you disconnect the load from the coil right after position B (or a tiny bit earlier) then you will have no output power?  Sure you will not have Lenz after position B but just because  you will not have useful output power for the "after position B" part of operation.

Regarding some schematics on timed switching, see this link, member Hoptoad has it: http://www.totallyamped.net/adams/  IT may be a long read, just take your time and I think you can learn from it.
