Magnet therapy takes many different forms. In some cases, magnets are applied to illness-affected areas with the help of wraps, shoe inserts, self-adhesive strips, belts, or "magnetic jewelry" like bracelets, necklaces, and earrings. Other products include magnetic mattress pads and blankets, as well as magnetic-field-generating machines and even magnet-conditioned water.

Since scientific support for its use is so limited, it's difficult to determine how magnetic therapy might promote healing. However, proponents maintain that magnets can stimulate circulation, relax the blood vessels, increase endorphin levels, reduce muscle tension, and normalize metabolic functioning.
