Please explain.

It is the one of besic faradayes law -when conductor cuts magnetic flux, EME induced in the conductor.

Hey @Sham but CHANGE IN flux causes induce an emf na. ?

Well just speaking the conductor can't cut the electricity or he will get shocked.

Change of flux produce emf & emf cause flow of current.

Alternatively when current flow in circuit it produce magnetic flux & changing magnetic flux produce current.

When movement of electrons happens, the current will flows. It is alone possible. But here I seen different parameter. Anybody have the ability? Let explain me.

Why you are differentiating the flow of electrons and Current,

All are similar just we are using the different terms, don't confuse yourself. I will explain in simple terms, change of flux induces EMF (in terms of Volt) i.e. is nothing but a flow of electrons or current and it also happens in vice-versa.

For further clarification please refer Faraday's law.

Whenever a conductor is moved in magnetic field or conductor is stationary and magnetic field is moving only then emf is emf is induced according Faraday's law of electromagnetic induction.

Either flux moves across conductor or conductor moves in flux, in both cases emf is induced due to this electrons inside conductor flows and these electron are responsible for flow of current.

Free electrons produces current when in movement caused by pressure.
