2014-7-1  The magnetic force on a particle in a magnetic separator may be controlled by varying the magnetic susceptibility of the particle/medium, the applied magnetic field or the magnetic field gradient. The size range at which magnetic separation is effective depends on which of the three main forces on a particle (gravitational, magnetic and fluid drag) is dominant at a particular size ( Oberteuffer, 1974 ).
