electromagnetic induction
1. Generation of an electromotive force, in an insulated conductor moving in an electromagnetic field, or in a fixed conductor in a moving magnetic field.
2. The production of electric current in a circuit when it is passed through a changing magnetic field.
3. Voltage produced in a coil as a result of the relative motion between the coil and magnetic lines of force; such as, flux linkages passing through the coil changes.
4. The production of an electromotive force in a circuit by the variation of the magnetic field with which the circuit is connected.
5. The generation of an electromotive force by changing the magnetic flux through a closed loop circuit, or by moving a conductor across the magnetic field.

This principle is the basis for the electric generator and electric motor.
