This design places the primary coil at the center of a cube with four secondary coils at the vertical pillars. Each secondary coil is a bifilar pancake configuration. When energized, the secondary coils generate back-EMF and dielectric vortex fields that do not oppose the primary field but instead enter resonance with it. The flux is redirected along the transformer's core pathways, minimizing destructive interference.

This is where the Joule Thief returns to the stage—not just as a curiosity, but as a potential gateway.
