What causes the magnetic curvature drift?

Johnathan K. Burchill

The curvature drift arises because a particle's gyration in a curving magnetic field is asymmetric, creating a net velocity offset.

The bundle contains the canonical record plus signed events. A mirror can host it anywhere and recompute the same current state with the deterministic merge algorithm.

Claims

C1strongest claim

The gyration is not symmetric about the field vector, and the resulting velocity offset is the curvature drift. This explanation is guided by Newton's second law of motion in vector notation and provides a common framework for the three guiding-centre motions.

C2weakest assumption

The convective rotation of the field along the particle trajectory ensures that the Lorentz force switches on and the resulting acceleration rotates the velocity vector back into alignment periodically.

C3one line summary

Curvature drift results from the Lorentz force triggered by convective rotation of the magnetic field along the particle trajectory, which produces asymmetric gyration and a velocity offset instead of a centrifugal guiding-center force.
