I still think the inside coil has to be spiral. It can't be round because there is no induction and no cutting lines of flux.
Make it oval or rectangular now it inducts but we still have varying magnetic intensity from a square or oval magnetic field.
But make the inside coil spiral, AhhHaaa.. It inducts and cuts the line of flux while keeping interesting magnetic features that may pose very useful.

Output looks good ?
Your 4 groups of magnets, do their poles alternate?
I would think that a coil on the inside as you described might just cancel, I'm not sure
If you make a sun gear you could have multiple core coils on the inside but spin the sun gear opposite to the rotor
thereby doubling your output.
Just thinking out loud
yo.
the poles are like this. 2 double chevrons making 4 diamonds. This pic is one double chevron. The rotor is that twice connected into itself.

And here is the coil core setting up. Epoxy and iron filings.

I should be able to get 2 of these coils in there crossing at a 90. I want to test a single before trying to figure that out though.

Now it's not as easy as spinning a spiral and slapping any old coil under it.. A coil's flux field has different intensity levels in different places. But there is a balance point where N is equal to S on opposite sides. Your spiral should also have balanced symmetry. The coils symmetry needs to match the rotors symmetry with respect to the coils orientation, length, poles, and symmetrical magnetic forces.
Hello there!
I hope you don't mind me butting into this conversation thread but I find your spiral magnet rotor designs quite interesting!
I have been learning about magnets, electromagnetism and whatnot for the past few months and I've been trying to find out if permanent magnet generators are actually possible (or even possible at all). After watching some of your videos, I became quite intrigued by this particular video of yours which leads me to one question: How come this rotor does not slow down to a stop when you spin it, unlike your previous (blue) rotor design?

Hello and welcome.
This rotor is much heavier than the other one with all the big magnets on it. So it takes more power to spin it initially, but the kinetic energy keeps it going like a flywheel because it is much heavier. It will still slow down though of course.

Ah I see.
By the way, have you ever thought of building a self-sustaining motor or generator? Like a motor that is driven by permanent magnets?

BTW, I'm curious... How many turns do you have in that huge coil of wire?

A LOT, LOL... It's like 2.5 pounds of 30 gauge. It can induct voltage from real far away but like no current. I wound it like this so when I test waves, I can see everything even when the magnetic fields are real small

Single strand copper wire? Is it enamel insulated or rubber insulated?
