A magnetic water treating device including a housing part containing a permanent magnet assembly with pole pieces positioned to contact the outside of a conduit, and having a flux return plate within the housing part at an outer side of the magnet assembly and spaced therefrom by a nonmagnetic part.

A magnetic water treating device including a housing part containing a permanent magnet assembly with pole pieces positioned to contact the outside of a conduit, and having a flux return plate within the housing part at an outer side of the magnet assembly and spaced therefrom by a nonmagnetic part. A pair of end plates at opposite ends of the magnet assembly desirably extend through openings in the nonmagnetic part into engagement with the flux return plate. Projections on the nonmagnetic part extend inwardly for locating the elements of the magnet assembly, and connector posts projecting from the nonmagnetic part may extend through apertures in a second nonmagnetic part at the inner side of the magnet assembly to secure these parts together. The flux return plate may be retainable in the housing by reception of an edge portion thereof behind a locating shoulder. A second housing part may carry a resilient structure for exerting yielding force against an opposite side of the conduit.
