Question

electromagnetic induction

Answer 1

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.

Answer 2

$\underline\bold{E.M.I.:-}$

​

Electromagnetic induction (E.M.I.) is the phenomena opposite to the magnetic effect of current. according to this induced EMF induced current are Step Up in a circuit kept in the varying flux.

The phenomena of inducing EMF or current in a closed circuit or loop as a result of varying magnetic flux linked with it is called as electromagnetic induction or EMI.

$\underline{\bold{Origination:-}}$

​

The origin of electromagnetic induction is the Lorentz Force that shift the electron from there position.

$\underline{\bold{Expression:-}}$

e is used to define Electromagnetic induction.

e is directly proportional to d¢/dt

e = - (d¢/dt)

This negative sign shows the opposing behaviour of emf
