Many sources on the web claim that when moving a conductor through a magnetic field, an emf is produced. However, some sources claim, that the intensity of the magnetic field also needs to change in order to produce a voltage over the conductor, for example: http://www.allaboutcircuits.com/vol_1/chpt_14/5.html What's the deal? Where lies the misconception? In my understanding, when you move a conductor through a uniform magnetic field, you have no rate of change of flux, hence you have no emf produced. Is this correct? Or am I wrong?
