It is electrical action produced by a non-electrical source, such as a battery (converts chemical energy to electrical energy) or generator (converts mechanical energy into electrical energy). It was coined by Alessandro Volta in the 1800s, when he invented the first battery, also known as the voltaic pile.
Sie fördert die Forschung zu technischen, biologischen, gesundheitlichen und sozialen Fragen im Zusammenhang mit elektromagnetischen Feldern von Funk- und Stromtechnologien. Physikalische Grundbegriffe von EMF (Forschungsstiftung Strom und Mobilkommunikation)
Die FSM berät Behörden, Firmen und Organisationen, veranstaltet Tagungen und vermittelt Sachwissen an die Allgemeinheit. The EMF or electromotive force is the energy supplied by a battery or a cell per coulomb (Q) of charge passing through it.
Difference between EMF and Potential Difference? Electromotive force is the electric potential generated by either a electrochemical cell or a changing magnetic field.

The magnitude of emf is equal to V (potential difference) across the cell terminals when there is no current flowing through the circuit. Energy is converted from one form to another in the generator or battery as the device does work on the electric charge being transferred within itself. Source: en.wikipedia.org.
A special type of potential difference is known as electromotive force (emf). It is also known as voltage. Electromotive force, abbreviation E or emf, energy per unit electric charge that is imparted by an energy source, such as an electric generator or a battery.
One terminal of the device becomes positively charged, the other becomes negatively charged. …
The emf is not a force at all, but the term ‘electromotive force’ is used for historical reasons.
Because the electromotive force is not a force, it is common to refer to these sources simply as sources of emf (pronounced as the … Die Forschungsstiftung Strom und Mobilkommunikation (FSM) ist eine unabhängige Stiftung mit Sitz in der Schweiz.
