nLab Lorentz force

Idea

The Lorentz force is the force exerted on a particle that is charged under the electromagnetic field.

See relativistic particle for details.

Properties

In Kaluza-Klein compactifications

If one models the electromagnetic field via the Kaluza-Klein mechanism as a field of gravity on a fiber bundle, then trajectories of charged particles subject to the Lorentz force in the base space of that bundle are euivalently just geodesics on the total space, e.g. (Bleecker 81). An exposition of this fact is in (Bartlett 13).
