STATEMENT-1: A copper sheet placed between the poles of an electromagnet (field perpendicular to the sheet) requires force only if the sheet is pulled out with increasing speed.
STATEMENT-2: The force required to pull a copper sheet out of a magnetic field increases with the speed at which it is pulled out.
