In gauge theory in physics a field configuration is modeled, in mathematics-terminology by a connection $\nabla$ on a principal bundle $P$ (or some associated bundle). In physics-terminology the connection $\nabla$ is sometimes called the **gauge potential** (while the equivalence class of $P$ is called the instanton sector and the curvature $F_\nabla$ is called the field strength).

Specfically in *electromagnetism* one also speaks of electromagnetic potential or *vector potential*.
