A magnetic filter in which an elongate ferromagnetic filter member is disposed within a housing having an inlet for fluid to be filtered and an outlet for filtrate with magnet means outside the housing for creating a magnetic field across the filter member. The member conveniently is in the form of an array of spaced apart bars of rectangular cross-section, the magnetic field being directed normal to the longitudinal axes of the bars and substantially parallel to the longer cross-sectional side of each bar.
