Hi folks, this thread is based on a simple generator principle that im sure others have already discovered, however after tests with a simple design i built it seems to work rather well and has very little cogging drag. I originally built it to test flux gate generator principles where a piece of metal or bolt in this case passes between a stationary coil-core and a stationary permanent magnet to generate voltage/current, however what I have found is that if the magnet is placed at the back or other end of coil-core the generated voltage is almost the same and the cogging drops to a very low level. So whats happening I assume is that as the bolt or iron, etc. passes the stationary coil-core with permanent magnet placed at back side of core, the neutral or bloch wall of the permanent magnets field is shifted more towards the rotor gap or just simply reduces the flux density in the coil-core and then expands again which emulates the expanding and collapsing magnetic field required for induction and with very low drag and no lentz drag either because only steel is rotating. If anyone else has experimented with anything similar or has any thoughts please share them, thanks. Here is a cad pic of the simple layout.

Hi Peter, thanks for reply. Not sure exactly what you built and tested, maybe if you described it in more detail your words would have more meaning, however i know for a fact this design and the flux gate completion designs cause no lentz drag because i have built both, so whatever it is you tested must not have have been the same or you overlooked something in testing. Also what your saying sounds plausible however understand that there is only one source of magnetic field and that is on the stator similar to Peter Lindemanns no back emf motors, the passive rotor steel does not cause counter emf or in this case lentz drag and even if as you say the rotor steel piece becomes magnetized and causes lentz it would have to saturate the steel, if not saturated it would tend to be attracted negating lentz. And since my results prove there is no lentz drag, theories only go so far in reality. Hope this helps to make more sense of things and you might want to do some more experiments.

Hi Peter, i just did tell my thoughts on the generators and it seems you would rather evade the points i made derived from  experimental evidence, if you would like to have a real conversation I'm here.

Hi Peter, I'm not sure the question your asking me. The voltage to current ratios would be a design choice.

Hi Skywatcher - thanks for sharing.
I'm of the notion to agree with petersone.

The bolt is becoming magnetized as it passes.  The will create a changing magnetic field in the coil, creating a (small) current.  The coil will create a field that OPPOSES the change, per LENZ.

I might suppose your setup is not large enough/enough coils/enough power to have noticed the LENZ drag?
Have you done a spin-down test?
Under identical spin/thrust conditions:
How long for the blank disk to spin-down?
How long for the spin-down with the bolts?

I think if you have better tests/measurement you will find that LENZ drag is still present.

Hi folks, thanks for replies. You know one of the gifts of life is you are given a choice to believe whatever you wish, even if reality is contrary to ones beliefs, however it is my opinion that each individuated soul finds it's own truth.
capt.hook: you may think whatever you wish, until you yourself build something for real you'll never know, all i can tell you is i have built other units that generated multiple amps and above 10 watts and still input amps did not change when loading generator coils. As for the spin down tests, removing the bolts would skew the tests results because of windage so not a good idea, also input amps only rise slightly when magnets are on the device compared to not on the device, hence very low cogging and with better core materials would be lower.
Hi Peter, I don't know what to say about the voltage aspect, maybe if you can relate some of your own hands on tests, that would help.

Hi Peter, well in this design and the other flux gate designs it would not matter what the ratios are to get 10 watts or 100 watts or 1000 watts as long as the mechanisms causing lentz to be a non-issue are adhered to. Perpetia i have replicated, and it works as Thane has shown, whatever the function, it's just that i wanted much lower cogging and no-lentz from the first rpm onwards so the idea I'm showing seems to work well. Granted power output is not very high yet but the potential is there. 

Hi Peter, I would imagine since I'm using steel bolts for now, it would probably have the same type of losses as normal generators, although different materials or laminates would help that. I was testing different things today like if more ferro material in the rotor pieces yields greater voltage in the coils and it does but probably only to a limit based on permanent magnets strength and saturation. Also It seems the current generated starts at almost no rpm at ramps up to almost the max current for the given coils with very little rpm. I lit a couple of leds to almost full brightness on the 2 coils while barely turning the rotor by hand maybe 100 rpm.
