Magnet therapy: Magnetic therapy, also called magnetic field therapy and bioenergy therapy, is an alternative therapy that uses magnets of varying sizes and strengths that are placed on the body to relieve pain and treat disease.
People who have medical devices or implants with a magnetic field, such as a pacemaker, should not use magnet therapy, because it could interfere with the function of the implant. Magnet therapy is not thought to have negative side effects or complications when it is combined with conventional medical treatment.
