What is electromagnetic induction?
(N/A) Electromagnetic induction is the phenomenon of generating an electromotive force $(EMF)$ or current in a conductor by changing the magnetic flux linked with it.
According to Faraday's law,the magnitude of the induced $EMF$ is equal to the rate of change of magnetic flux through the circuit,given by $\varepsilon = -\frac{d\Phi_B}{dt}$.
This phenomenon is the fundamental principle behind the operation of electric generators,transformers,and induction motors.
