Information
Magnet therapy, magnetic therapy, or magnotherapy is an alternative medicine 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. These claims are both physically and biologically implausible and no effects on health or healing have been established. Although hemoglobin, the blood protein that carries oxygen, is weakly diamagnetic and is repulsed by magnetic fields, the magnets used in magnetic therapy are many orders of magnitude too weak to have any measurable effect on blood flow.
Magnet therapy is the application of the magnetic field of electromagnetic devices or permanent static magnets to the body for purported health benefits. 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 jewelry; magnetic straps for wrists, ankles, knees, and the back; shoe insoles; mattresses; magnetic blankets (blankets with magnets woven into the material); magnetic creams; magnetic supplements;and water that has been "magnetized". Application is usually performed by the patient.
