Faraday's Law of Induction

Definition

Faraday's Law of Induction states that a change in magnetic field induces an electromotive force (emf) in a closed loop, resulting in the generation of an electric current. In simpler terms, it explains how moving magnets or changing magnetic fields can create electricity.

Analogy

Imagine you are riding a bicycle and suddenly hit a bump on the road. The jolt you feel is similar to the induced emf when a magnet moves near a wire. Just as the bump causes your body to move, the changing magnetic field causes electrons to move within the wire.

Electromotive Force (emf): It refers to the voltage or potential difference generated by Faraday's Law of Induction.

Lenz's Law: This law states that the direction of an induced current will always oppose the change that caused it.

Magnetic Flux: It represents the amount of magnetic field passing through a given area and plays a crucial role in Faraday's Law of Induction.
