There is always a magnetic field on earth. From the above definition, all water are magnetized???
Please provide a scientific definition.
And do you find any different between "magnetized water" and "non-magnetized water"?
Or: is it just a claim without any evidence?
I found the following informattion from wikipedia:[url=http://en.wikipedia.org/wiki/Magnetic_water_treatment]Magnetic_water_treatment[/url]
Magnetic water treatment is a proposed method of water softening.
The tools for magnetic water treatment are often sold by home distributors, who have made dubious claims of effectiveness. Proponents of the method assert that powerful magnets sandwiched over a water line, so the water passes through the magnetic field, will treat the water without the need for chemical softening agents. They also make unsupported claims that the shapes of the mineral molecules in hard water are sufficiently modified to eliminate the build-up of calcium and lime, and also remove limescale already present in the system.
Sellers of the technology also make unsupported claims that treatment of water with magnets can treat blood circulation, prevent or cure disease, increase the strength of concrete, and prevent tooth decay.
Vendors have pictures and testimonials pertaining to their claims, but there are several scientific studies that refute the effectiveness of the method. Consumer Reports carried out a two-year experiment with two water heaters; the end result showed no evidence of any benefit.
