Self-Induced Precession and the Larmor Analogy
A striking, though often misleading, analogy exists between the motion of a vortex filament and the Larmor precession of a charged particle in a magnetic field. A curved segment of a vortex line induces a velocity component perpendicular to its own axis, causing the entire segment to move bodily (translate) in the direction of its curvature. This self-induced motion leads to complex helical trajectories.
When a vortex experiences a non-uniform backgro…
