Answer 2

The electromagnetic induction discovered by Michael Faraday.

(3) is correct option.

Explanation:

Electromagnetic induction :

Electromagnetic induction is equal to the rate of change of magnetic field.

Michael Faraday is discovered of the Electromagnetic induction in 1831.

Electromagnetic induction is defined in mathematically term

$\epsilon=-\dfrac{d\phi}{dt}$

Where, $\epsilon$ = electromotive force

$\phi$ = magnetic flux.

The direction of the electromotive force is given by Lenz's law.

Hence, The electromagnetic induction discovered by Michael Faraday.
