The SEP is not a vector field, but is a scalar field. Indeed, scalar potential cannot of itself perform work on a charged mass due to the extremely high SEP of the vacuum itself. Only a differential of SEP between two spatial points can produce force

Story behind the song
The SEP is not a vector field, but is a scalar field. Indeed, scalar potential cannot of itself perform work on a charged mass due to the extremely high SEP of the vacuum itself. Only a differential of SEP between two spatial points can produce force or accomplish work. (Rigorously, a differential of scalar potential between two spatial points constitutes a vector. Only a vector can produce force and do work.)
