Abstract: Disclosed are electromagnetic apparatuses for separating non-ferrous blanks, methods for making and for using such apparatuses, and automated systems with electromagnetic destacking unit for handling stacks of non-ferrous blanks. Presented is a destacking unit with a magnet placed adjacent a stack of non-ferrous blanks, and two electrical terminals placed in contact with the top blank of the stack. The magnet generates a magnetic field across the surface of the top blank. The terminals pass electrical current through the blank transversely across the top surface. The direction of the electrical current is generally normal to the direction of the magnetic field such that a magnetic separation force sufficient to displace the blank from the stack is generated in a generally vertical direction.
