Abstract
Abstract An apparatus for the treatment of water which includes an elongated magnet having a multiplicity of longitudinally spaced poles enclosed in an inner casing of non-magnetic material, the latter being received within an outer casing of magnetic material and in radially spaced-apart relationship thereto. The apparatus is further provided with novel porting and the magnet, non-magnetic casing and outer casing are dimensioned and proportioned to provide improved fluid flow thereabout.
