For better efficiency in removing scale and deposits in pipes, a high gauss permanent magnet unit, requiring no servicing or external power, mounts on the exterior surface of the pipes for establishing a flux path encompassing a greater portion of the flow path than heretofore feasible. Even more effectiveness results from mounting units in diametrically opposed pairs. The units have a pair of alnico magnetic plates straddling an arc on the pipe surface to focus the magnetic flux into a preferred pattern into the fluid flow path. By blending two permanent magnetic circuit paths from different permanent magnetic materials offering different advantages, a multi-pole, multi-axial magnetic flux generator uniquely distributes and concentrates the magnetic forces for maximum de-scaling effect. Standard units fit different diameter pipes, provide very high fluid treatment flux concentrations over a wide range of pipe cross section area and have long life in the presence of magnetic interference or electrical shock.

In a dynamic magnetic fluid flow treatment system for controlling scale and deposits having a set of permanent magnetic cells for surrounding a cylindrical pipe defining a fluid flow passageway, wherein the permanent magnetic cells comprise in combination: a cylindrical pipe having a longitudinal axis; a pair of parallel spaced apart longitudinally disposed alnico permanet magnet plate members polarized in a direction parallel to the longitudinal axis of said pipe; ceramic ferrite permanent magnets positioned respectively near the N and S poles of and between the alnico plate members to extend substantially perpendicular to the longitudinal axis of said pipe, the ferrite permanent magnets being polarized in a direction perpendicular to the longitudinal axis of said pipe; and; a low reluctance not permanently magnetizable magnetic circuit plate member disposed substantially parallel to said pipe spanning the two alnico plate members and disposed longitudinally over the length of the alnico magnet members and adjacent a N pole of the ferrite permanent magnets; all magnets and the magnetizable plate member being assembled as a single unit with the two alnico plate members providing a pair of extending legs straddling an arc on said cylindrical pipe and respectively abutting the pipe along their length to induce inside the pipe a generally longitudinally oriented magnetic flux pattern encompassing substantially a sectorial area through which fluid flows.
