Scalar and vector potentials

In vector calculus, a vector potential is a vector field whose curl is a given vector field. This is analogous to a scalar potential, which is a scalar field whose gradient is a given vector field. Formally, given a vector field v, a vector potential is a vector field A such that WebChapter 10: Potentials and Fields 10.1 The Potential Formulation 10.1.1 Scalar and Vector Potentials In the electrostatics and magnetostatics, the electric field and magnetic field …
