➪ What is electromagnetic induction?

$\huge\bf\green{*Aŋʂwɛr༉}$

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

Formula :-

$e = N × dΦ / dt$

Where,

• e is the induced voltage (in volts)
• N is the number of turns in the coil
• Φ is the magnetic flux – the amount of magnetic field at a surface (in Webbers)
• t is the time (in seconds)

Answer 2

Answer:

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.
