A clamp-on magnetic water treatment device for minimizing hard precipitate scale and lime deposit in a fluid supply, especially a domestic water system, has a magnet array having two sections which clamp together over a non-ferromagnetic section of conduit in the water system. The array of magnets defines at least two pairs of magnetic poles of opposite polarity across the flow path for the water, whereby a magnetic field is produced defining flux lines directly perpendicular to the flow path, and the magnets in the array attract one another across the flow path. The magnets in the array also define magnetic poles of opposite polarity proceeding downstream along the flow path. However, the individual magnets in the array are all arranged such that their poles are directed toward and away from the conduit, and not longitudinally along the flow path. In this manner, the maximum field strength is obtained in a clamp-on device. An outer enclosure of ferromagnetic material confines lines of flux to high permeability materials, maximizing flux density at the area of the fluid flowing in the conduit.

A clamp-on fluid treatment device for minimizing accumulation of hard lime and scale deposits in a water supply system having at least one conduit for carrying the water along a flowpath, the conduit having at least a section along its length which is non-ferromagnetic around its circumference and characterized by low magnetic permeability, the device comprising: an array of at least four permanent bar magnets to be mounted on a surface of the conduit at the non-ferromagnetic section, the array of bar magnets abutting one another longitudinally of the conduit and defining at least two pairs of magnetic poles of opposite polarity across the flowpath, whereby a magnetic field is produced directly perpendicular to the flowpath and magnets in the array attract one another across the flowpath, magnets in the array also defining magnetic poles of opposite polarity proceeding downstream along the flowpath, each of the bar magnets defining a magnetic pole directed toward the non-ferromagnetic section of the conduit and an opposite magnetic pole directed away from the non-ferromagnetic section, the bar magnets individually being nonpolar in a direction parallel to the flowpath, poles of successive ones of the bar magnets on a same side of the non-ferromagnetic conduit being at opposite polarities proceeding along the flowpath, whereby a charged particle moving along the flowpath is subjected to alternating Hall Effect forces, tending to agitate the charged particle and interfere with hard lime and scale precipitation; and a housing for the magnets, the housing being magnetically permeable and defining a magnetic flux path encircling the conduit and bridging between outward facing opposite poles of the magnets, the housing having two substantially semi-cylindrical halves, each said half having a bottom section magnetically attracted to a pair of said magnets on a respective side of the pipe, the magnets being disposed between the bottom section and the non-ferromagnetic section, the housing having wings extending outwardly from the bottom section and from the non-ferromagnetic section of the conduit, the wings defining supporting flanges at which the two halves of the housing are supported in contact along a plane including a longitudinal axis of the non-ferromagnetic section, the halves of the housing being magnetically attracted to one another at facing edges thereof, the halves of the housing have flanges extending radially and parallel to the flowpath, the halves being disposed in surface contact at the flanges, whereby the magnets are positioned opposite one another on the non-ferromagnetic section of the conduit and magnetic flux is confined to the housing and to the flowpath.
