Hi Dog-one
"Replacing the short with something that increases magnitude of current flow but keeps current flow in same ditection"
You wrote this a few posts back....could this be a FWBR?
Perhaps instead of actual short circuit of neighboring coil, instead a very heavy, very "useful" resistive/capacitive load such as supercaps on DC side of FWBR??
Maybe single diode or half bridge rectifying energy into super caps would do the trick too...

If one uses a shorted (or a heavy load like a discharged supercap to our) FWBR, it creates the proper 2X frequency bumps necessary for parametric resonance.  However I'm pretty sure we need more than this.  We need to push current into the second winding, not just create a short.

Simplicity is best, but I'm pretty certain what we need can be done with active components.  From what I can see so far, Pierre found a way to use caps, diodes and switches to get the proper results.

I've spent hours today working Bode Plots trying to find the right combinations.  There's a bit of magic in there still, but I'm starting to see patterns we can take advantage of.

If you could copy the magnet, would the setting of the coils be the same?

and let's add a move to it.

If each subsequent coil was supplied with increasing and decreasing voltage, we would have such a magnetic field.

The movement of the field itself will not be able to do anything, and the change in inductance will only affect the field's power, just like to increase the voltage. The same can be achieved by one or two coils. You need to look even deeper.

The relays in Pierre's setup was not altering amount of current going through individually. The paralel overlapping coils was making variation of the flux strength when 2 coils at once was turned on.
Ideally you want to have as many paralel coils turned ON as the diameter of output core is which was 4 coils with single North or South poles. Then change positions of the edge coils for forward movement.

P.S. Even where are 4 coils all ON they are connected in series so +/- 1 coil does not alter flowing current a lot.
