What is electric induction

Electromagnetic Induction was discovered by Michael Faraday in 1831 and James Clerk Maxwell mathematically described it as Faraday’s law of induction.

Electromagnetic Induction is a current produced because of voltage production (electromotive force) due to a changing magnetic field.

Electromagnetic or magnetic induction is the production of an electromotive force across an electrical conductor in a changing magnetic field. Michael Faraday is generally credited with the discovery of induction in 1831, and James Clerk Maxwell mathematically described it as Faraday's law of induction. Electromagnetic Induction is the governing principle that is used to explain how electric generators (also called alternators), microphones, electric guitars, and transformers operate.

The current contained in the conductor is said to alternate because its current flows back and forth, as a result of the conductor being first raised and then lowered in the magnetic field. In short, currents help to create magnetic fields.

A moving or changing magnetic field does produce a current in a current loop or a voltage across the ends of a current loop. This is called electromagnetic induction and the current or voltage is called an induced current or an induced voltage.
