electromotive force

Rusty lead, so to speak, so connected with bright lead, has a high electromotive force.

Now whenever an electric conductor cuts magnetic lines of force an electromotive force is induced in the conductor.

If the coils are rotated in a magnetic field, each will produce an electromotive force.

Electromotive Force, the name given to the force tending to produce a flow of electricity in an electric circuit.

For a discussion of the electromotive force produced by thermo-electric action, see Thermo-electricity.
