EMF, or electromotive force, refers to the voltage created by a battery or by a changing magnetic field.
Introduction to Electromotive Force. Voltage has many sources, a few of which are shown in Figure \(\PageIndex{2}\). All such devices create a potential difference and can supply current if connected to a circuit. A special type of potential difference is known as electromotive force (emf). The emf is not a force at all, but the term ...

The electromotive force EMF of a source of electric potential energy is defined as the amount of electric energy per Coulomb of positive charge as the cha rge passes through the source from low potential to high potential.

The electromotive force E(abbreviated emf) is the voltage produced by a source of electric field, such as a battery or a time-varying magnetic field. Although it is called a ’force’ it actually has the dimensions of energy as it is defined as E= fd‘‘ (1) where f is the total force per unit charge and the integral is taken around
The minus sign in Faraday’s law indicates that a changing magnetic flux will induce an electric field and current such that the B the current produces leads to a flux change
