Lenz’s law of electromagnetic induction states that
- a force is exerted on a current-carrying conductor in a magnetic field
- electromotive force id induced in a circuit whenever there is a change in the magnetic flux linked with the circuit
- the magnitude of the induced electromotive force in a circuit is proportional to the rate of change of flux linking the circuit
-
the induced current in a coil is in such a direction that it sets up a magnetic field which opposes the change producing it
