@callanan
Thanks for your videos.

When i saw the one with the tremendous cogging

I wanted to suggest to use a dissimilar number of stators/toroids and rotor magnets, such as a setup with 4 magnets (spaced at 90° from each other) and 3 toroids (spaced at 120° from each other).
In this way not all coils and magnets would align at the same time, but each pair would align at a different time during one revolution.

But then I figured, that in order to do this, each torus would have to be triggered/energized/masked at a different point in time, so several trigger switches would be necessary. This seemed to make things difficult, so I did not post.

But now, that you found the solution of winding a trigger coil onto the torus, you could do that for each torus, so that each one is triggered individually and maybe a configuration as I described becomes more viable.

.... Much to my disappointment, my coil did not release the this magnet, nor even the smallest magnet I could test.

I fear I must have missed a fundamental concept in winding toroids.

I also thought like you, but it seems not to be a prerequisite, that the toroid actually releases a stuck magnet.
As you can see in the videos of those who have built it, there is quite a big air-gap between the toroids and the passing magnets.
And the magnet arrives with a certain speed. It seems to be enough to weaken the attracting field between torus and magnet. The toroid's attracting field does not have to be completely nullified, as far as I understand.

If your magnet doesn't release increase the amperage or increase the distance of the magnet from the core.

A number of people have suggested adding a generator, the simplest generator I know of is a
stepper motor,used in old computer printers,floppy drives.

Yes the magnet wheel was fake but that generator was real

@Penno 64 .I t is not clear from your posting , wether your failed winding is a single wire , or a multifilar wind . If it consists of say 4 strands, you may have got the ends wrongly interconnected , so that the magnetic fields of some strands oppose and cancell others , Giving a net field of zero . Interconnect them like this . Each strand has a start end {A] and a finish end B. When the winding is complete all the A ends will be in one bunch , and the B enda in another . Pick an A end wire at randon and label it "start" . Use an ohm meter or battery and test lamp to pick its other end , and connect this end to another wire from the A bunch [NOT the B group.] Now with one test lead on "start" go to group B and find the single wire that forms a circuit with "START"  connect that wire to any spare A group wire . Continue this process untill you have only one spare wire in group B .Label this  END. Job Done. In other words although the strands are in series,  the current in each strand must always flow in the same direction ,either all A to B or all B to A depending which way round you connect the battery . Hope this helps.
