I too had a design similar to this, with flux blocker coils turning the array field on and off to one side only. I didn't realize reversing the fields of the second and fourth magnets shifted the field from side to side, but I see it now. Thank you for the enlightenment. With this concept, even a simple pendulum generator should be several times overunity. Wraping an output coil directly around the three magnet and two electro magnet array might generate even more. Wraping the electro magnet solonoid coils bifilar, would double the magnet strength for the same power.

It looks like you would need several separate coils working independently given that the flux lines are so awkwardly placed in the array.  It looks like if you just wrapped it in a coil, it would defeat itself since half of the lines would counter the other half.

Great idea Void109!! I have been trying to play with this design some, but I'm running low on wire. It will probably be awhile before I can order more. Anyway... Here is a quick drawing of what I think your talking about here. I also included a possible way to tie the outputs together without the output of one side of the Halbach array putting power to the coils on the other half. I call it a phase rectifier, it's just a full bridge rectifier for each 'phase'.

Picture a Hallbach array sandwiched between two rotor wheels with staggered iron cleats attached along the edge of each of the insides, above and below. Activating the second and fourth electro magnet would make the Hallbach magnetic field shift from side to side with double the strength, attracting first the overhead then the staggered rotor cleat beneath; like the Art Porter design, a different coil assisted magnet motor, with a five to one pay off, strength doubling on each side! The Tesla bifilar high volatge magnet coil is wraped exactly like a Joule Thief, two wires three ends. The beginning of one wire attached to the end of the other. Twice the magnetic strength of a single wrap solenoid for the same wire length and input!   

Void's idea is most intriguing. Obviously, the power consumed by the electromagnets
will be crucial. Maybe the device can be used to get a SMOT ramp into a circle.
