If a conductive material is moved through a magnetic field in a direction perpendicular to the lines of said magnetic field, an EMF will be generated within the conductive material. The EMF will be proportional to the speed at which it is traveling and the strength of the field. The EMF will be at right angles to both the direction in which it is traveling and the lines of the field.
This will occur regardless of whether the source of the magnetic field is in motion relative to the conductive material or not.
(Again, disagreements are welcome, though it might be tricky to discuss in depth without something to drawpictures diagrams on...)
EDIT: As
reedrover pointed out below, I failed to clarify one small but very crucial detail: in both cases the conductive material is in motion relative to the observer.
