A further difference between magnetic and electric forces is that magnetic fields do not net work, since the particle motion is circular and therefore ends up in the same place. We express this mathematically as: W = ∮B ⋅ dr = 0 (21.4.5) (21.4.5) W = ∮ B ⋅ d r = 0.

Abstract. Magnetic separation is based upon a competition between a number of forces. To explain its principle [1, 2] it is convenient to refer to the diagram shown in Fig. l.

In this regard, the physics of magnetic separation at the microscale is not unlike that of gravitational sedimentation, or sedimentation in a centrifugal field, in that the range of separation is bounded at the small particle size limit by the randomizing effect of thermal motion, and also strongly depends on the separation-specific property of the …
