Write down the names of two devices which work on the principle of electromagnetic induction.
(N/A) The principle of electromagnetic induction states that a changing magnetic flux through a coil induces an electromotive force $(EMF)$ in it.
Two common devices that operate on this principle are:
$1$. $AC$ Generator: It converts mechanical energy into electrical energy by rotating a coil in a magnetic field.
$2$. Transformer: It changes the voltage level of an alternating current using the principle of mutual induction between two coils.
