Question

what is electromagnetic induction . give a very simple define . and also this image question too

Answer 1

hey friend

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 inductionI

Answer 2

Hola User__________________

Here is Your Answer....!!!!

⤵Actually welcome to the concept of the EMI

⤵Basically when we talk about the MAGNETIC FIELD through any closed surface ...so then the MAGNETIC FILED lines passing throughout the surface causes The

⤵Magnetic flux ...that is given by

⤵phi (B) = B .dA

⤵so ..actually when the Magnetic flux is changing throught continuously in the body .... there is generation of the induced ELECTOMOTIVE FORCE in the body ...due to which the INDUCED CURRENT IS FORMED IN THE BODY ....

⤵Thus the Rate of change of the Magnetic flux in a body with respect to time which causes induced emf is called as the Electromagnetic Induction .....
