Magnetic water treatment

Magnetic water treatment (also known as anti-scale magnetic treatment or AMT) is a disproven method of reducing the effects of hard water by passing it through a magnetic field as a non-chemical alternative to water softening. A 1996 study by Lawrence Livermore National Laboratory found no significant effect of magnetic water treatment on the formation of scale. As magnets affect water to a small degree, and water containing ions is more conductive than purer water, magnetic water treatment is an example of a valid scientific hypothesis that failed experimental testing and is thus disproven. Any products claiming to utilize magnetic water treatment are absolutely fraudulent. |access-date=2009-12-11

Vendors of magnetic water treatment devices frequently use photos and testimonials to support their claims, but omit quantitative detail and well-controlled studies. 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. |access-date = 2009-12-11 |url-status = dead |archive-url = https://web.archive.org/web/20120417131247/http://www.wcponline.com/pdf/0804Keister.pdf |archive-date = 2012-04-17 |access-date=2007-10-26 |archive-url=https://web.archive.org/web/20090727010107/http://www.csicop.org/si/9801/powell.html |archive-date=2009-07-27 |url-status=dead |access-date=2009-10-25 |archive-url=https://web.archive.org/web/20080501194133/http://www.chem1.com/CQ/magscams.html |archive-date=2008-05-01 |url-status = dead |archive-url = https://web.archive.org/web/20111215092211/http://www.wbdg.org/ccb/ARMYCOE/PWTB/pwtb_420_49_34.pdf |archive-date = 15 December 2011
