In electrodynamics (using Newtonian space and time) the magnetic field is represented by a vector potential A. In order to describe the electric field, we need another scalar quantity called the scalar potential. 2/13
In special relativity, the scalar & the vector potentials can be combined into a vector potential but this potential is a four-vector. This potential which has one index is called a 1-form (or one-form). 3/13
