ugg, here I am again.

Although I do not like public transportation vehicles of limited length with a pedantic drive. I do want to get closer to the optimum generator.

So I did some field tests using my tesla meter and am not sure yet how to interpret the data.



this is a repelling setup at it minimum with 4 of my test magnets. I use the same magnets for all measurements in the same order

 

with help from contributions here I was able to print something stronger.

 

now for my collected data

hmm how to proceed.

ugg, this is looking terrible. You guys do not even know yet where the measurement points are and I am already risking wrath. ;( Sorry. I will have to perhaps think of this blog feature I think I saw earlier down the line.

 

You still don't seem to get it. Your magnets are the wrong way to get any real results for electric generation. Putting them pole to pole like your doing actually cuts the amount of magnetic field lines that can interact with the coils. Doing it your way you only are getting the fringes of the magnetic field, not the "heart"(don't know the correct term) of the magnetic field.

Unless your magnets are made different than the normal magnet of that shape. Give a real link or a picture of how the poles of those magnets are orientated.

Your spread sheet is also meaningless to any one but you. You don't explain what/where the measurements are.

I'll try giving more relevant data. please give it some time.
But what I can say already is that the magnets are neodisium n42 class with dimensions 60x10x5. The seller posts that they have a 12KG holding capacity but I have no idea how to translate that to anything I can read with my tesla meter.

This is the original repelling disk though having a similar space between magnets as a traditional magnet at minimum distance arrangement would allow.

 

Do you understand that it is not the strength of the field going through the coil, but rather the change in strength over time that produces the output current?

Hmm I think I am only just now might start understanding what it is you are going at.
That could well mean this endeavor is fruitless.

Although I am still certain that field strength is a factor in the equation I have not taken things from this angle yet.

 

Most magnets that are sold by a REAL magnet supplier, not an Amazon or Ebay seller will show you how the poles are oriented in their web site. Like these guys do for a similar looking one like you have -

Now look at the concentration of the field lines in a magnet, the greatest number of lines comes from the poles not the edges. Photo -

And stacking (forcing) magnets with the same orientation next to each other only makes a weird looking field. Alternating them and giving enough space so each end would prefer to interact with the stator coil than a neighboring magnet will be key to your design. The goal is to make AC current, that means alternating which pole of the magnet is over a stator coil.

 

it are these magnets

With magnetic field lines as I have drawn earlier in post #8 and can be seen by my iron powder photo.

agreed, but that is exactly what this test is about. Trying something unusual to see if it can benefit

Ok, well, your "trying something unusual" has about the same chance of success as my grandson attempting to put water in my lawnmower's gas tank to see it it will run. It made sense to him.

Lessons learned though experience are lessons learned best. Enjoy your learning experience.

I really do not like it when people, especially from the old school, just say things. without any support.

I al least am trying to support where I am coming from.

It's 2022 everybody!!

I didn't know I needed support. Lenz's law first introduced in some middle school science classes (as a concept) when motors/generators are first introduced and then in depth (with math) in high school physics class. Current is induced in a while as it passes in/out (though) a magnetic field. This was mentioned in an earlier post - I assumed you saw it.

 

Ohh I'd like to get back on topic again please and expand with a coil winding question.

Would there be a difference between individually wound coils (48 of them) or a serpentine wound one in terms of voltage potential?

Serpentine would be easiest to DIY

I will run experiments then with both arrangements. traditional and repelling.

I guess that would at least help settle this endless focusing on an aspect that I never asked about to begin with.

I will really respect if we can focus on the aspects I do really need help with.

We were focusing on the magnet arrangement because it will be way more important than the minor question about how to wind the stator.

hi q,
It would help if you posted a summary of the aspects of the Project, for which you are requiring help.

All three windings generate the same voltage:
