I am testing out a new idea in hopes of bypassing Lenz.  The main concept is to move the magnetic field around in the coil without moving the magnets or the coils, thus the back EMF can not hinder the motion of the magnets.

6 big Neo's will be aligned with 6 iron core coils. All magnets and coils will be static (non-moving).  Between the coils and magnets will be a spinning rotor that has 12 laminated iron strips that will pass between the magnets and coils.  The laminated iron strips will deflect the magnetic field as they pass between the magnets and coils, thus generating AC current. I plan to keep the magnets alternating in hopes of preventing permanent magnetization of the iron strips.

The Hopes:

I hope Lenz becomes a non-starter because the magnets nor the coils are in motion. 
I hope Eddy Currents will be minimal because the iron is laminated strips from a transformer
I hope it will be able to generate some usable output.

The Possible Cons:

The gap between the magnet and the coil will be less than optimal because I have to pass hunks of iron between them.
Eddy Currents MAY still be a hinderance
Power production will probably be less than optimal
I have no idea about possible saturation or it's effects
Many other unknowns.

Hi floodrod!
For defeat Lenz , in rotation devices : components of magnetic flux receive and generate must no movie ! motion is flux path only or motion virtual !
Sorry for my English !

A possible problem you may run into is the gap between your rotor arms. The gap seems kind of small for the width of the magnets it looks like you are using. If that is the case, the flux will possibly jump right from one arm to the next without jumping much if any into the coil core. If you don't get much voltage at all, you may need to remove every other arm to give more gap for the flux to jump to the core. Only testing will tell.

A clarification might be that when the ferrous rotor approaches as magnet,  it would become momentarily a magnet and will behave as such from a Lenz point of view.

Thanks everyone for the great comments so far.

I have the magnets and metal strip disk mounted, and am now working on designing a coil mount.  What I notice so far is that the metal strip disk spins rather freely over the magnets.  There is a small degree of minor cogging, but the weight of the disk (from all the metal) acts as a flywheel and the cogging is barely noticed.  Eddy currents seem to be not of concern with the laminated iron.

Kolbacict- you are correct- the magnetic influence is the spinning disk alone is not much of a problem. It spins quite freely.

Paul's comment on the metal bars becoming magnets is certainly a possible negative..  I can already see when an iron strip is over a magnet, the metal strip is definitely magnetized. A bolt wants to attract to it. There are too many possible variables and fine details I can not measure or predict.  But it is quite possible Lenz will act against the spinning metal strip disk.  From initial observations, it seems a hanging bolt wants to attract to the center of the magnet regardless where the metal strip is.  I am assuming the flux is weaker over the iron than in the surrounding air so I am not sure how that old crochety man named "Lenz" will react.

Captain-  The spacing of the arms may be very important as you suggest. Currently, when 1 arm is almost past the magnet- the next is already in. There is a point in the current design when 2 different arms are at each edge of the magnet. Power production is 1 aspect, but lenz drag is another.  I really have no idea or prediction on how and when the interactions will take place. It will be difficult removing iron though..  These iron slabs could cripple a person if they come loose, so I epoxied them with JB Weld for safety.  Removing them is probably off the table..  If I do experiment with that- I would have to replace the disk totally.

Mounting the coils is becoming a project in itself.  I don't want to have wood or material between the coils and the metal strips, so I need to attach mounting legs on each coil design this so I can dial in the gap.  It's going to be a little sloppy for this test build- but I can get the alignment decent I am sure.

Hopefullu later today I will have more info

Are they in series already? There are a few really good ways to boost the voltage anyway, so I wouldn't be to concerned about that yet if you are seeing some reasonable current. It's enough voltage to work with. Even a simple voltage multiplier capacitor circuit could easily do it. I've also seen the output going right into a step up transformer before with no electronics at all. Total watts of course is important as you know. But I would say the first test is looking great.


One thing you could keep in mind also if you end up wondering about the arm spacing. The further out to edge the wider the gap. That field will jump a good distance. You could always move the magnets outward another inch or so just sticking out beyond the arms. They will pull that flux in anyway if you don't go to far beyond. If possible though I would move the coils as well.  This is of course only something to consider if you have to make changes already.

Hi all !
Ah! I got it , but amplifying output?

Floodrod, I have experimented with a similar setup.  Your metal plates are too thick and too narrow.  They need to be wide enough to completely cover the coil and only about 1/8th of an inch thick.  And the gap between the plates and magnet and between plate and coil needs to be much closer.  Between coil and plate needs to be about the thickness of a piece of cardstock.  And the gap between the plate and the magnet needs to be about 3 times that depending on the strength of the magnet.  If you make those changes you will be surprised at what you get.


Good luck and keep trying and learning.

PS: You are correct in keeping the magnets of alternating polarity to keep the plates from becoming magnetized.

Thank You..  If I run across some good material that would work as a disk, I may revisit this.
