Abstract: A device for treating fluids with magnetic lines of force includes an electrically isolated non-magnetic, metallic conduit through which the fluid passes. An electromagnetic coil surrounds the conduit and is electrically insulated from the conduit. The coil is clad with a magnetic housing or shunt, and fins surrounding the coil dissipate heat generated by the coil. A core consisting of a single cylindrical magnetic section or a series of endwise connected alternating short sections of magnetic and nonmagnetic material is disposed within the conduit along the conduit's axis at a location which is offset downstream from the coil. A helical baffle located between the conduit and the core, or, alternately, a driven impeller, provides circular flow for the fluid so that the fluid crosses the lines of magnetic force extending between the ends of the core and the metallic shunt in a 90.degree. relationship therewith.

Abstract: A device for treating aqueous solutions with magnetic lines of force includes a pipe through which the solution passes. An electromagnetic coil surrounds the pipe and a core consisting of endwise connected alternating short sections of magnetic and nonmagnetic material is disposed along the pipe's axis. Located between the pipe and the core is a helical baffle.
