Braided Magnetic Flux Ropes in Modern and Ancient Symbolism
Braided magnetic flux ropes. What is modern on image A and B is also on ancient symbolism. The center flow path being biggest and straightest, the side flows are attracted to it, but cannot touch it because of the prickly fiery outflowing pressure from the tube wall surfaces, that you see on image G and H.
Caduceus and chakras being 2D diagrams of 3D structures where flux ropes can have more than two side flow strands. The side flows will want to curl, and if the curl goes clockwise, those outer flux tubes can flow in either direction as long as they curl the same way.
As far as I can tell, each flux tube only flows in one direction, and only when a center flow path reaches it's destination, then can a side flow tube follow it back to the source, establishing "bidirectional" entanglement/ connection.
Not shown on this post, but I'll mention this: the way a flux tube wall is built up by interlinked little tori, gives it the properties it needs. Little tori, some point outward, some inward, and some sideways. That gives some magnetic attraction, some repulsion when tubes get too close, and some "paramagnetic" adaptability to settle into the optimum separation of the center flow from the side flows.
