The therapeutic use of magnets may be older than acupuncture, originally involving a material called magnetite applied in a poultice. Today’s magnet therapy is still applied to the skin, but employs steady or pulsed magnetic fields from either electromagnets or less powerful permanent magnets. Fixed magnets may also be taped to the body for a period of time. Magnet therapy is used to relieve pain and discomfort and to aid in healing with a variety of physical and emotional disorders, such as arthritis and stress. Treatment may be administered by the therapist or, as in the case of taped magnets, by the client.
