This paper investigates the mechanisms of extraction of ferromagnetic bodies from a stream of bulk material by suspended magnets. It is shown that the force density, usually used to evaluate a suspended magnet, can give erroneous criteria for the magnet design and that the magnetic field strength is the primary parameter in evaluating a suspended magnet.
