... What’s the difference between motional emf and induced emf ? “Induced emf” is the more general term. By Faraday’s Law, you get an induced emf whenever there’s a changing magnetic flux through a loop. If the changing emf is due to some kind motion of a conductor in a magnetic field, you would call it ...
