Copper bracelets are still being sold, keeping alive the old superstition that they could alleviate arthritis and rheumatism. Some models also include magnets to enlist their supposed pain-relieving power as well.
Magnetism was believed to "draw out" pain, and one popular superstition involved placing a horseshoe magnet at the bottom of one's bed, the prongs pointing toward the feet, as a cure for leg cramps. Today, magnetic therapy is a fad among some professional athletes and others who purchase magnetic pain-relief products, including magnetic bead necklaces and magnet-studded neck and wrist wraps, shoe inserts, etc. (see James D. Livingston, "Magnetic Therapy: Plausible Attraction?" Skeptical Inquirer, July/August 1998, pp.25-30.)
