Magnetic water treatment (also known as anti-scale magnetic treatment or AMT) is a controversial method of supposedly reducing the effects of hard water by passing it through a magnetic field, as a non-chemical alternative to water softening. Scientific studies into the efficacy the treatment have had mixed results, though several studies have produced significant effects and proposed possible mechanisms for the observed decrease in water scale. Some commentators regard the treatment as unproven and unscientific.
Magnetic treatments may be cheap and chemical-free, but there is little firm evidence of their effectiveness in domestic situations. Effective treatment has mainly been observed in industrial situations where there is constant cycling of water through the device. The treatment only claims to alter the effective hardness of water; no solutes (such as calcium or magnesium) are removed from the water by the process.

Famous quotes containing the words magnetic, water and/or treatment:
“We are in great haste to construct a magnetic telegraph from Maine to Texas; but Maine and Texas, it may be, have nothing important to communicate.”
—Henry David Thoreau (1817–1862)
“If water is too clear, it will not contain fish; people who are too cautious will never gain wisdom.”
—Chinese proverb.
“Ambivalence reaches the level of schizophrenia in our treatment of violence among the young. Parents do not encourage violence, but neither do they take up arms against the industries which encourage it. Parents hide their eyes from the books and comics, slasher films, videos and lyrics which form the texture of an adolescent culture. While all successful societies have inhibited instinct, ours encourages it. Or at least we profess ourselves powerless to interfere with it.”
—C. John Sommerville (20th century)
