Especially, their trajectories can be bend when a strange beast is applied to them. This strange beast is called a magnetic field. The natural object to make bending and (eventually) closed trajectories is by rolling a physical particle in a curved potential. The curvature of this potential is $F$ for the charge. It explains how charges trajectories bend in space(-time). But since it is a property allowed to charge only, it has the gauge structure as well. | |

| Mar 24, 2014 at 18:36 | comment | added | Christoph | geometrically, it's a Lie-algebra valued 2-form representing the curvature of a principal connection and thus describes the obstruction to integrability of the horizontal subbundle; depending on your mathematical background, I suspect this comment is rather unhelpful... | |
