Why is a >60 Hz alternating field more deleterious than a steady state From memory, the Earth's magnetic field is 5 microTeslas, and since 1 Wb/m^2 is 1 T, large fractional Wb would be more powerful than 5 microT. Thus there would be more physiological effects due to the 60 Hz radiation. I also heard that anemia may be induced by 60 Hz radiation (again, from memory, no references) Greg Harrison My opinions are not intended to reflect those of GE.
