Magnetic separation is a process used to separate materials from those that are less or nonmagnetic. All materials have a response when placed in a magnetic field, although with most, the effect is too slight to be detected. The few materials that are strongly affected (magnetised) by magnetic fields are known as "Ferromagnetics", those lesser ...

where μ 0 is the permeability of free space and M is the volume magnetization. In the absence of an external magnetic medium, the H-field lines are identical to B-field lines outside a magnet (the stray field) and only differ by a factor μ 0, (B = μ 0 H); but inside they point in a different direction. B is solenoidal (∇⋅B = 0), meaning that its field lines always form closed …
