ABSTRACT:
An electromagnetic lifting device comprising a plurality of electromagnets having a variety of individual magnetic pole face areas and an inverted generally U- or W-shape connected with each other and further rigidly connected to a suspension member, and specifically adapted to electromagnetically lift up only a single sheet of ferromagnetic metal sheet by energizing a selected one or plurality of the electromagnets to an extent of necessary and enough electromagnetic energy in accordance with a thickness of the single sheet of metal and exerting thus-produced electromagnetic force to that single sheet of metal so that only that single sheet of metal can be lifted upwardly away from a pile of such metal sheets.
