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)
