ABSTRACT:
A set of magnetic assemblies for treating fluids including water and liquid and gaseous fuels wherein each assembly includes a construction of permanent magnets and pole pieces arranged to optimize a "Figure of merit" number defined as the integral of the absolute value of magnetic field intensity over region occupied by the fluid. In one embodiment, each assembly includes an elongated magnet with permeable pole pieces at each end bent back toward each other to form a gap equal to one half the length of the magnet. In another arrangement, each assembly includes a permanent magnet having a pole piece leading around toward the flux surface at the other end of the magnet, adjacent to the fluid carrier. Dimensions of the area of the pole end surface are selected based on the permeability of the pole piece, magnetization intensity of the permanent magnet material and pipe diameter to maximize the Figure of merit. Figure of merit is maximized by placing an odd number of assemblies around the conduit. Fluid flowing in long lengths of pipe is treated by arranging assemblies on the pipe spaced from one another by a distance equal to the flow velocity times the lifetime of the treatment effect.
