But there is something else to this.
In the attraction mode, I would pulse the first drive coil of the pair so the pulse starts at the coil exterior winds. This puts the field instantly outside the coil so it can attract the approaching magnet. Then go to the second drive coil pair again from the outside inwards.
In the repulsion mode, I would pulse the first drive coil of the pair so the pulse starts at the coil interior at the core itself. This puts the strongest field at a pin-point near the TDC to repulse the magnet away from the drive. Then go to the second drive coil again from the inside.
To accomplish the above, you may need to turn your coils around and not just switch wires. I had been trying to explain this ever since this started but @MH kept on insisting I was a dreamer.
It is very simple. Nothing in this build endeavor should be permanent until and the facts are known. All you need is a compass and a DC power supply to figure it all out and get the coils oriented properly and connected properly.

I forgot about this.
The pulse that starts on a drive coil pair on let's say north side of rotor, then the pulse on the other coil pair should start on the south polarity. Meaning one coil pair receives the pulse from the top coil first while the other drive coil pair receives the pulse from the bottom coil first. This is because when you pulse two coil in series, the second coil will never have the same field strength as the first coil in the pair and in order to keep the motive energy one both polarities equal. Otherwise the rotor may start to wobble.
You can test this very easily by using only one drive coil while the second is not mounted but still in series. See how fast you can get the rotor to turn. Then try it by switching the wires around. Then try it by turning the mounted coil to the other side, then again by switching the wires around. Everything you try has to be in fours otherwise you are working in the dark.
But for all intents and purposes, guys have to realize that the coil have to ends. Near core end and far core end. Then they have two polarities. Then they have two coils per drive set, all making for known variables.
