Lenz's Law
Definition
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.
Analogy
Imagine you are trying to push open a door while someone else tries to close it from behind with equal force. Your efforts cancel each other out and keep the door closed. Similarly, Lenz's Law acts like someone pushing back against any changes in magnetic fields, preventing them from easily occurring.
Related terms
Faraday's Law of induction: 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: 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.
