well , w/e freq that allows highest voltage you get 5 or 10 turn pots and sweep
i dont feel resonance is key here , pulsed opposite magnetic fields from bifilars is what does the work on the water
Explain further pls. The magnetic field does not directly go through the wfc, also both fields annihilate themselves if connected as for example the Dave Lawton circuit recommends. So the energy stored in the inductors is nearly zero. How can that perform any work?
Bifilar inductors are wire resistors.
