The obvious example of three magnetic interference waves, becoming stuck into a knot (unstable hotspot) or ball lightning start. which was the reason to search for a particle system able to merge into knots for different functions. Fermion and Black hole ( ball lightning) knots.
The form and different ring diameters: 1: 7 is best, with little bending of rigid transformer strings for smooth compounding.
Visible light is able of small focusing, reason to start with laser interference into knots for micro ball lightning black holes.
Evidence for the compound Ball Lightning Nucleus, able to split by falling through tree. also in video. see:
MONO POLE EVIDENCE, for two magnetic string quantum waves.
The propeller fermions are milling stones of vacuum particle rings into photons of different types. see:
CALABI YAU BY ROTATION OF PROPELLER FERMIONS.
The typical dual tadpole shapes in space supporting the Penrose Vuyk Model.
An other evidence for the repulsion of self made plasma tail fermions inside the pushing tadpole tail of the comet like knot.
