The fluid dynamics of electromagnetism

RSI treats electromagnetism as the meshing of twisted knots, not an abstract force. Charge is not a built-in number but a Toroidal Displacement Direction, the sense in which a knot's wake twists. It is counted in thirds of a turn: a full left-handed turn is the electron's charge of −1. When two knots meet, their flow fields either mesh or clash under the 0.73 N field tension.

Opposite twists behave like gears in sync. The medium flows smoothly between them, the pressure between them drops, and the knots draw together. This is the attraction of opposite charges. Matching twists raise the pressure between the knots and push them apart, which is electrostatic repulsion. Either way the force weakens with the square of the distance, steadily and without loss, as Coulomb's law requires. Deriving that law from the medium is an open goal.

Charge, the twist, is not the same as spin: two electrons with opposite spins still repel.

Magnetism, in this view, is a bulk current of the medium moving through aligned knots. The right angles of the Right-Hand Rule come from the Lateral Vortex Wake: a moving electron churns the medium in a circle perpendicular to its path. Conservation of charge becomes conservation of pressure. Each negative twist (an electron) requires an equal anti-twist elsewhere to keep the 0.73 N baseline.
