Physics:Magnetic water treatment

From HandWiki
Short description: Unproven method of supposedly reducing the effects of hard water

Magnetic water treatment (also known as anti-scale magnetic treatment or AMT) is a method of supposedly reducing the effects of hard water by passing it through a magnetic field as a non-chemical alternative to water softening. Magnetic water treatment is regarded as unproven and unscientific. A 1996 study by Lawrence Livermore National Laboratory found no significant effect of magnetic water treatment on the formation of scale.[1]

Vendors of magnetic water treatment devices frequently use photos and testimonials to support their claims, but omit quantitative detail and well-controlled studies.[2] Advertisements and promotions generally omit system variables, such as corrosion or system mass balance analyticals, as well as measurements of post-treatment water such as concentration of hardness ions or the distribution, structure, and morphology of suspended particles.[2][3][4][5][6][7]
