Hi Ye'All: After the several posters about Magnetic health benefits, I decided to look up my old physics text. My conclusions are that it all looks like a gigantic hoax if not outright fraud. But if spending money on this kind of frivolity might give happiness to some, go for it. Earth, our unique planet, has a magnetic field of about 1/2 G (Gauss); the applied field described in some therapies is 1 (one) pico tesla. With 1 PicoTesla=10(-9)G x 10(4)G= 10(-5)G or 1 Pico Tesla = 10 to the minus 9 Tesla 10 to the 4 Gauss = 1 Tesla therefore 1 Pico Tesla = 10 to the minus 5 Gauss which means that in order to receive 1 Pico Tesla, you would need to sit 50 miles away from the magnetic source. That is hugely trivial; you can get a far greater amount of magnetism by just waiting for it in your waiting room. Should anyone be interested in other similar financial investments, I have many other sources available. One that stands out is the Brooklyn Bridge, which I have not been able to dispose of to my satisfaction. Good luck! Michel
