Abstract

A device for the magnetic separation of a fluid including first particles to be separated of magnetic or magnetizable material and second particles of non-magnetic or non-magnetizable material may include at least two magnet arrangements for generating a magnetic induction B, which are arranged in line with one another with regard to a center axis M, wherein neighboring magnet arrangements have an opposing pole arrangement and are arranged at a distance d from each other for the generation of a cusp field. The device may also include at least one conveying line for transporting the fluid, the line having a longitudinal axis extending, at least in the region of the magnet arrangements, on a plane aligned perpendicularly in relation to the center axis M between neighboring magnet arrangements. The conveying line(s) may have at least one branch downstream of the center axis M, along the transporting direction of the fluid.
