Definition of electromotive force in English:

electromotive force

(also emf)


  • A difference in potential that tends to give rise to an electric current.

    • ‘The inductance of the loop is going to resist the change in magnetic field within it and an emf will be generated.’
    • ‘One can view such structures as miniature circuits: A time-varying magnetic field induces an electromotive force in the plane of the element, driving currents within the conductor.’
    • ‘When this happens electrons move an electromotive force such as voltage, and in hitting these atoms, also create heat via friction of the electrons and atoms.’
    • ‘The immune system responds with an opposing behavior, a net electric energy gradient or electromotive force, which is brought about by complicated intracellular processes.’
    • ‘From the graph, the mean leak conductance and the mean transcellular electromotive force were estimated.’
