Canceling Lenz's Law - Methods

EDIT nevermind, I was wrong.  Not my day...

Small but important correction on the updated pic. Cosequently this arrangement will have very small output, all covered by Lenz. Picture this arrangement in your head as hydraulic system with turbine in the middle leg of the core and magnets as flow source/sink. Immediately it becomes apparent that water/flux wont like going thru middle leg very much...

Its not actually the magnets altering the cores field as shown.

As the 2 magnets are approaching a wound core as shown, the magnets fields are still bound to the previous core like rubber bands, then the flux fields kinda jump over to the new core from the previous core.

As that is happening, the sides of the cores where the windings are open, the magnets fields 'cut' the windings, inducing currents in the windings. It does so when the magnets field is leaving the previous core, and jumping to the next core. But the coils field is trapped in the core, having no direct link to the magnets fields, other than affecting the cores attraction to the rotor magnets when the coil is producing its field in the core.

Neat idea.     Probably best to have short cores, as in the rotor magnet wheels have as little spacing as possible.  This way the magnets fields are stronger passing the cores and dense where the windings are being cut.

Whether or not it is possible to "cancel" Lenz's
Law or the difficulties it entails doesn't seem
likely.

There are ways to avoid invoking the Law,
however.  Find a way to isolate the load
from the prime mover by means of magnetic
switching and the problem will be largely
solved.

The MEG was one approach but it is flawed.

The QEG or Zimmerman's Composite Generator
may offer the ultimate solution.  Surely, some
innovation and modification will be needed.

Hi guys

This is my attempt for the E shape core.

I foto 1 there are 3 small transformers (220V primary; 2x12V secundary) with a 4 mags rotor.
Edy currents from the laminated E core were to big to spin it up over 1000 rpm (12V input;200mA).
Even so the output from the transformers were high in voltage and very low on amperage:
-35V from the primary
-6V from the secundary ( each transformer has a FWBR and they were in parallel)
The current that i measured over 1 ohm resistor was very low
-0.2mA from the primary
-3mA from the secundary

In dead short there was no effect on the rotor but also the output was very poor so I pased to the next config:

In foto 2 there are 2 coils that spin the rotor and a E shape ferite core with a coil that came from an 220V electromagnet.
Since now there is no edy currents, the rotor spins much faster around 2000rpm.
The output is around 7V at 1000rpm and again the amperage is very poor around 2mA.
In dead short there is a small decresing in rpm witch raises the input current with 10mA.
So I put some magnets on the core, trying different ones and the output went up 30V.
Didn't mesured the curent but it could spin only a 3V small dvd motor.
In this case lens was there decreasing a lot the rpm and the input curent increased with 40mA.

From this experiment I can say that lens is still there but somehow is a bit different.

I will experiment more with this kind of core, trying some thiker wire like 0.5mm

Wow, looks great.


Usually, low output is due to little coupling and small interaction volume. Your PMs seem rather small. They should flood the entire coil. normally the E Cores may be problematic for a big PM because they include a closed loop path, in simple terms, the magnetomotive force goes from south to north in the inside of the coil, and back to south on the outside. But maybe you did something really smart here: you are deflecting the back mmf. The magnet induces a current in the coil, so far so good, Lenz did not show up yet, all fine. But now the current in the coil causes a magnetic field in the core, and that would cancel out the PMs field in a normal motor. But with the EE core the Back mmf may just go trough the outer core and keep on circulating.


So you may have killed Lenz already, to some degree. It may be the nature of such devices to have relative small output, yet basicly at overunity. You may think about to buy 2 pounds of metglass and create yourself some similar E cores, featuring superhigh permeability,allowing for much better performence in such a design.


An other thing you can try is a cap in series with the driver (when it is AC), this will bring consumption 90° out of phase. Capacitance must fit, so the entire wave gets trough, even although with phase shift.
