How are magnets used in attempts to treat pain?
There are two kinds of magnets used in pain treatment: Static magnets are usually made from iron, steel, rare-earth elements, or alloys. Typically, the magnets are placed directly on the skin or placed inside clothing or other materials that come into close contact with the body. Electromagnets were approved by the FDA in 1979 to treat bone fractures that have not healed well. Uses of electromagnets are still considered experimental by the FDA and have not been approved. Currently, electromagnets to treat pain are being used mainly under the supervision of a health care provider and/or in clinical trials.
