A spacetime one-form whose exterior derivative or curl is the electromagnetic field strength; gauge-related potentials represent the same local field strength.

Each relation below starts at this concept.
This is an authored directed relation from the source endpoint to the target endpoint.
The measured phase depends on enclosed flux, represented by a Wilson-loop or line-integral phase of the potential.
The source theory, law, entity, prediction, or structural claim is directly tested, supported, constrained, or established by the target experiment or observation. Experimental support is not final logical proof; the edge detail states exactly what was measured.

Locally, the electromagnetic field strength is the exterior derivative of the four-potential; global topology may require multiple gauge patches.
Apply a standard functorial or canonical construction whose output is not merely a reduct of the input and is not generally an equivalent presentation of the same object.
