${\green {\underline {\underline {\mathcal {What\: is\: Electromagnetic\: Induction...?}}}}}$​

Answer 1

${\large {\bf {Electromagnetic \ Induction :}}}$

➠ The current produced by a voltage production due to the change in magnetic field is called electromagnetic induction.

$\qquad \diamond$ It is discovered by Michael Faraday.

$\qquad \diamond$ Alternate current (AC) Generator works on the principal of electromagnetic induction.

❖ Formula for the electromagnetic induction :

$\large \red {\underline {\boxed {\sf Formula \ : \ e \ = \ N \times \dfrac {d \theta}{dt}}}}$

Where,

e = Induced voltage.

N = Number of the turns in a coil.

t = time (in sec).

$\sf \theta$ = magnetic flux.
