Description

In this context, "force" refers to potential energy per unit of charge, measured in volts, rather than mechanical force, which is measured in newtons. The electromagnetic work that would be done on a charge if it travelled once around a closed loop is known as the Electro-Motive force (emf) in electromagnetic induction. Due to the circulating electric vector field, the electric potential scalar field for a time-varying magnetic flux linking a loop is not specified, but an emf still exists and can be measured as a virtual electric potential around that loop. The amount of electric energy per Coulomb of positive charge as the charge is the electromotive force EMF of a source of electric potential energy.
