    (54) Magnetic separators


    (57) A filter (10) for removing magnetic particles from a fluid stream comprises successive sub-sections (11-14) along the length of the filter each having a distributed pattern of permanent magnet particle collectors (20) and fluid flow apertures (40), this pattern being different in the sub-sections such that the collectors of the successive sub-sections together cover the whole cross-section area of the filter and such that the apertures of the successive sub-sections together define meandering fluid flow paths through the filter.
