The Geomagnetism Home is now at: http://www.ngdc.noaa.gov/geomag/geomag.shtml

The Magnetic Field Calculator's are now at:

Compute the Field Values - 7 parameters for a single point.
Declination calculator - simpler form computes only magnetic declination.
New! Now you can compute field values for an area.
See the instructions page.
