Lenz's Law states that when there is an induced current or EMF in a circuit, its direction will always oppose the change causing it. This law ensures conservation of energy and plays a crucial role in understanding electromagnetic phenomena.
Faraday's Law of induction states that a change in the magnetic field through a loop of wire induces an electromotive force (EMF) in the wire. It is closely related to Lenz's Law as it describes the generation of EMF due to changes in magnetic fields.
Magnetic flux: Magnetic flux refers to the measure of how much magnetic field passes through a given area. It depends on both the strength and orientation of the magnetic field lines relative to the area.
Electromagnetic induction is the process by which a changing magnetic field induces an electric current or electromotive force (EMF) in a conductor. Lenz's Law is one of the fundamental principles governing electromagnetic induction.
