    I was wondering what the magnitude is of the earth's magnetic field? Or perhaps websites that may help to determine this magnitude for specific places on earth. thankyou

    A Google search for "earth's magnetic field" gave me this on the first page:

    http://www.ngdc.noaa.gov/seg/geomag/magfield.shtml [Broken] from the National Geophysical Data Center.

    The global magnetic strengths of the earth have been decreasing for several thousands years.
    Especially during the last 10 years all kind of measurements have taking place from satellites.
    But so fare I haven’t find any available data showing exactly what have happen to the GLOBAL magnetic field the last 10 years. I mean is the global magnetic field still decreasing, - if yes, - how much month by month / year by year .Does someone have tips where such available data can be found? – Or are such data at all available for everyone ? thankyou
