An object is to provide a lifting magnet that can secure a sufficient magnetic flux penetration depth during conveyance of steel plates, easily and highly precisely control the magnetic flux penetration depth in accordance with the number of steel plates to be lifted, achieve both a high level of performance of controlling the number of steel plates to be lifted during control operation and a high level of lifting stability during conveyance, and has a compact and lightweight device structure.A lifting magnet includes a plurality of electromagnetic coils 1 that are concentrically arranged 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 can secure 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.
