Recently, my friend W turned saleman tried to sell me his products. What did he try to sell me? Cushions with magnets implanted in them, and magnetic bracelets. W claims the use of magnets can improve blood circulation and cure ailments, such as asthma. He even cited the use of MRI (Magnetic Resonance Imaging) as proof to its effectiveness.
What a load of rubbish! Yes, there is iron in blood, but it is in ionic form. Irons ions do not exhibit ferromagnetic properties. In fact, there is no hard evidence to prove its effectivenss. Check wikipedia! Oh, and MRI is a complete different animal, using vibrations rather than poles to obtain imaging!
