Some suppliers recommend applying magnetic patches directly to your aches and pains, while others recommend applying small Band-Aid-like patches to acupuncture points. Magnetic belts containing sixteen or more magnets are purported to ease back pain, and similar magnetic wraps are offered for almost any part of the body, including hands, wrists, elbows, knees, ankles, and feet (magnetic insoles are particularly popular).

For headaches you can wear magnetic headbands, magnetic earrings, or magnetic necklaces. (One company marketing magnetic necklaces provides simple instructions: the necklace should be put on as soon as the headache appears and removed as soon as it goes away. Since most headaches come and go, following these instructions precisely will clearly produce persuasive evidence of the necklace's efficacy.)
