Magnetic Separation SpringerLink

In analogy with other methods of separation based on physical properties, magnetism can be used for separating materials which respond more strongly to a magnetic force from other materials which exhibit a less strong response. In any given separation it is customary to describe the two products as “magnetic” and “nonmagnetic” respectively.
