Holding Magnets-2

Part of Stephenson Gobin Ltd. A British Engines Group Company SG Transmission Ltd. Bishop Auckland, County Durham UK DL14 0HY Stephenson Gobin Ltd. manufactures a wide range of general purpose holding magnets for demanding industrial applications. Holding electromagnets are magnetic devices with steel bodies and internal coils used to securely hold ferromagnetic parts once the coil is energised. The magnets are energised to hold, where electric current is required to turn the magnet ON. Power is then removed to turn the magnet OFF. The holding forces of the securing magnets are largely dependent...
