Question

Explain the elctromagnetic induction in detail....???​

Answer 1

Answer:

production of current by relative motion between a magnet and a coil

Explanation:

➟Electromagnetic induction is the production of current by relative motion between a magnet and a coil.

➟The phenomenon of producing electric current in a conductor by moving it perpendicular to a magnetic field or vice -versa, is called electro magnetic induction.

➟Electromagnetic induction is used in transformers, AC generators and choke coils.

➟This phenomenon is responsible for induction of voltage in secondary coils in transformers and for induction of voltage due to change to flux through the coil in AC generators.

➟Choke coils are inductors used to block higher-frequency alternating current (AC) in an electrical circuit, while passing lower-frequency or direct current (DC).

➟However a room heater works on the principle of power radiated by passing current though a resistor in accordance with the Ohm's Law.

Answer 2

$\huge\underline\mathfrak\purple{Answer}$

Electromagnetic induction

The property of production of voltage in a conductor by a changing magnetic flux is termed as electromagnetic induction.

It was discovered by Michael Faraday in the 1830s.

The main use of elctromagetic induction is to power many electrical devices.
