Abstract:
1. A fluid treatment device for fluid activation including at least a pair of permanent magnets arranged around a fluid passage extended through a casing and using a magnetic force of the permanent magnets for activating fluid flowing through the fluid passage, the treatment device comprising: a conductive metal layer interposed between the fluid passage and the permanent magnets and formed from a non-magnetic material enclosing the fluid passage; and a tubular magnetic material layer totally and solidly enclosing the permanent magnets thereby preventing the magnetic force of the permanent magnets from leaking out of the casing, wherein the paired permanent magnets are closely spaced from each other in a predetermined angular relation and define a gap therebetween and wherein one of the permanent magnets presents its north pole to the fluid passage and the other permanent magnet presents its south pole to the fluid passage.
