Beschreibung
Zusammenfassung:	A lifting magnet including a plurality of electromagnetic coils that are disposed in a nesting arrangement and capable of being independently ON/OFF-controlled and voltage-controlled. By using the plurality of electromagnetic coils in a selective or appropriately combined manner, the lifting magnet secures a sufficient magnetic flux penetration depth during conveyance of steel plates, and can easily and highly precisely control the magnetic flux penetration depth in accordance with the number of steel plates to be lifted.
