ABSTRACT:
An electromagnetic lifting device is provided with a pole piece of tapered or conical configuration extending outwardly from the load contacting surface of the magnet body. The tapered or conical configuration of the pole piece extends the effective magnetic flux pattern outwardly of the magnet body and also enables the pole piece to penetrate more readily into a collection of loose ferrous articles which are to be lifted.
