Magnets, for some reason, are magnets for bogus science...ridiculed as such since Mozart had Despina use her magical magnet to cure ills and revive the Albanians in Cosi Fan Tutte ("This is the magnet, the Mesmeric stone that originated in Germany and became so famous in France" -- it sounds more lyrical when sung in Italian).
I do know several people, however, who claim that magnetic vests have helped their backpains...go figure
