>From what I have researched the earth is slowly loosing it's magnetic
field and at the same time expanding in size. These two things occuring
at the same time would make sense since the earths magnetic field
is partly formed from solar radiation pressure - ease off the solar
radiation
and the earth would expand. Now the schumann frequency deals with
the earths natural resonances and since the earth is expanding the natural
frequency should be lowering. Our earths polar radius is presently around
6356.912 km which would place the schumann frequency at 7.51Hz, assuming
2*pi*R = lambda.
