Definition:

The Induction Effect refers to the production or generation of an electric current or electromotive force in a conductor when it is exposed to a changing magnetic field.

Explanation:

The Induction Effect is a fundamental principle in electromagnetism, discovered by Michael Faraday in the 19th century. It states that a magnetic field that varies in strength or direction can induce or create an electric current in a nearby conductor.

Process:

This effect occurs due to the interaction between the magnetic field and the electrons present in the conductor. When a conductor, such as a wire, is placed in a changing magnetic field, the magnetic field lines cut across the conductor, causing the free electrons within the conductor to move.

Electromotive Force (EMF):

The movement of these free electrons in the conductor creates an electric current, resulting in the generation of an electromotive force or voltage. This induced current flows in a direction that opposes the change in the applied magnetic field, following Lenz’s law.

Applications:

The Induction Effect is utilized in various devices and technologies. Some common applications include electric generators, transformers, induction coils, and wireless charging systems. It is also the underlying principle behind the functioning of electric motors and many types of sensors.
