What is electromagnetic induction in a conductor?

When a conductor cuts through the magnetic lines if flux, an EMF is generated across its ends.


If the circuit is closed, we can reasonably expect an electric current flowing through the conductor when there is a change in magnetic flux through the closed conductor.

Even of the conductor is closed, an EMF is generated.
This can be well explained by using Lorentz force acting on electrons in the conductor due to movement of the conductor relative to the magnetic field.

In general, a changing magnetic field generates an electric field in space perpendicular to it. An electric field implies an EMF.
