Relitivity (Electromagnetic Four Potential) Retarded potential. Four Current (Relativity) Electromagnetic four-potential. Lorenz_gauge (Electromagnetic Four-Potential) Mathematical descriptions of the electromagnetic field. There are various mathematical descriptions of the electromagnetic field that are used in the study of electromagnetism, one of the four fundamental forces of nature.
In this article three approaches are discussed, generally the equations are in terms of electric and magnetic fields, potentials, and charges with currents. Vector field approach[edit]
