The current induced in a circuit, caused by its motion in a magnetic field or a change in it's magnetic flux, in such a direction as to exert a mechanical force opposing the motion or to oppose the change in flux.
Direction of current induced in a conductor, by any change in the relation between the conductor and a magnetic field, opposes by its own magnetic field the action tending to induce the current.
A physical law that states when the current through a coil changes, an induced voltage is created in a direction to oppose the change in current. The current cannot change instantaneously.
The current induced in a circuit due to a change in the magnetic field is so directed as to oppose the flux, or to exert a mechanical force to oppose the motion.
