Final answer:

Motional EMF is induced by motion relative to a magnetic field and follows Lenz's law. Faraday's law of induction governs the EMF induced by a change in magnetic flux.


Explanation:

Motional EMF is induced by motion relative to a magnetic field, given by emf = Blv. This phenomenon is governed by Lenz's law, where the opposition to a change in flux induces an electromotive force (EMF) in a coil. The Faraday's law of induction states that the EMF induced by a change in magnetic flux depends on the change in flux, time, and number of turns of coils.
