This document summarizes the design, construction, testing, and performance of two "Vortex Coils" designed for wireless energy transfer and other applications. Key findings include: 1) The coils were tested for electrical parameters like inductance and resistance, and their frequency response was measured with no load, showing resonant peaks where output voltage was highest and phase shift lowest/highest. 2) Coil 1 had a resonant peak at 27kHz with minimum phase shift, while Coil 2 peaked at 674kHz with maximum phase shift. 3) The coils were also tested as motors, showing vibration and rotation at lower frequencies up to 25Hz driven by a function generator and magnet.

The vibrations and rotations were
observed at lower frequencies up to
25Hz, above which the vibrations
were undetectable by touch and
sight

11. Conclusion
• 2 coils with different configurations, one was powered like a step up
transformer
• The frequency response of the first coil showed no load resonant
peaks at 27kHz at which phase shift was minimum.
• The frequency response of the second coil has no load resonant
peaks at 674kHz at which phase shift was maximum.
