Superconducting magnetic separator (Patent) | OSTI.GOV
Magnetic separation is a physical separation process that segregates materials on the basis of magnetic susceptibility. Because the process relies on physical properties, separations can be achieved while producing a minimum of secondary waste. Most traditional physical separation processes effectively treat particles larger than 70 microns.

Magnetic separation. The increasing use of magnetic solid carriers in biochemical and molecular biology processes has many advantages compared to other non-magnetic separation processes. The term 'magnetic' means that the support obtains a magnetic moment when placed in a magnetic field. Thus, it can be displaced.
