Magnetic therapy or magnetotherapy is an alternative medicinal practice involving the use of static magnetic fields. Practitioners claim that subjecting certain parts of the body to magnetostatic fields produced by permanent magnets has beneficial health effects.
The therapy involves the application of the magnetic field of electromagnetic devices or permanent static magnets to the body for purported health benefits. These benefits may be specific, as in the case of wound healing, or more general, as for increased energy and vitality. Some practitioners assign different effects based on the orientation of the magnet; under the laws of physics, magnetic poles are symmetric. Products include: magnetic bracelets and jewellery, magnetic straps (for wrists, ankles, etc.), shoe insoles, mattresses, magnetic blankets (blankets with magnets woven into the material), magnetic creams and water that has been "magnetized". Application is usually performed by the patient.
Magnet therapy is considered pseudoscientific due to both physical and biological implausibility, as well as a lack of any established effect on health or healing.
