Question

Describe about electromagnetic induction.

Answer 1

⭕️Electromagnetic induction means the phenomenon of generation of emf in a conductor.

⭕️The process of inducting current by changing magnetic field is known as electromagnetic induction.

⭕️There are two ways to induce current on a coil. Either move it in magnetic field or change magnetic field across it.

⭕️Convenient way is to induce current is to move coil inside magnetic field.

⭕️ fleming's Right hand rule is used to find direction of induced 

⭕️This can be done by varying the magnetic flux associated with it.

⭕️This can be done by moving the conductor in the magnetic field, or by varying the magnetic field associated with the conductor.

⭕️ Transformer, motor, generator etc are working according to the principle of electromagnetic induction.

➖ or..

⭕️Electromagnetic induction: the phenomenon of inducing current by varying magnetic field.

Answer 2

ANSWER

ELECTROMAGNETIC INDUCTION


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 production of current in a conductor as it moves through a magnetic field.

A magnet produces lines of magnetic force, as seen in the graphic above.

Iron filings align themselves along the invisible lines of flux.
