A try to eliminate Lenz's forces.
That was similar to daniel quale generator. Even though it has less lenz effect in my understanding this setup doesnt produce so much flux change as a result the induced voltage is not so great.
@Neo-X
I saw the design of Daniel Generator. He has used a single shield (inductor) to cut off the flux in the ring magnet in front of the coil. When you use a single shield, it has to be very thick to absorb the flux completely. Hence you have to provide larger gap between magnet and coil. As a result coil receives weaker flux at a distance hence induced voltage will be less.
But when you short north pole with south pole, the shield you use need not be very thick. You can manage it with very little gap between magnet and core. When north and south poles are shorted, you will get 100% shielding hence the core generates high voltage and high power output as in the case of a standard generator. But instead of making ON and OFF of the flux you have to achieve reversal of flux which can be done easily by suitably arranging magnets and shield.
My question is whether the shield experiences any slowing down lenz 's force when moving between magnet and core.

When you spin the metal shield, it will create it's own lenz that will slow down.
The pick-up coil will generate it's own magnetic field that also affects the rpm of spining metal shield. These are the results of my own experiments with this kind of generators.

If you dont laminate the metal shield, it will surely produce its own lenz. Now if you want to know if the laminated metal shield can still have lenz effect i all i can say is i dont know the answer but my guess is it dont have or have less.. Only experiment can provide the answer.

Whenever you place North and South face of magnets on opposing sides of coil, you end up with very LITTLE amount of power. Flux cancels and no power is generated. I don't believe it will work, sorry, but would encourage you to try, as that is how we learn.

I believe that this setup is an ecklin brown flux gate generator, which is said that when the generator is loaded the rotor speeds up making it a lenzless generator....

His setup does not produce much power because he used ferrite speaker magnets, if neo mags are used it is posible to get more...

In that case none of the generators in this world should work. Because in all generators north and south poles are shorted through the coil. When polarity is reversed it produces AC wave in the coil. Open a generator and see.

You really must play with magnets and coils more. To produce "electricity" of ANY amount, the coil must see a change of flux. EXCEPT in the case of a unipolar generator which is an entirely other subject.
If you take a north magnet above a coil, and a south facing coil below the identical coil, and pass the coil through, the way that you have drawn the coil, having a magnet on either end, it will not work. I have tried it in real life many ways, and the flux cancels, the coils sees no change of flux or very LITTLE and LITTLE power is produced. Please, feel free to try, if you still do not believe me. I would love to find a way to do that and be proven incorrect. ;)

Just compare that drawing with a transformer. Is not north and south poles are shorted in a transformer? How does a transformer work?
Remove the top and bottom of a transformer then it will resemble the coil which I have drawn. Then if you create variation of flux with north pole on one side and south pole on the other side, it has to generate power like a transformer isn't it?
