Magnetic Field Calculator

The Magnetic Field Calculator will calculate the total magnetic field, including components (declination, inclination, horizontal intensity, northerly intensity, easterly intensity, vertical intensity) and the annual change for each. Each calculation is for a specific location, elevation and date or range of dates. The calculated result can be obtained from two separate geomagnetic models, the IGRF11 or the WMM2010. Declination is calculated using the current World Magnetic Model (WMM) or International Geomagnetic Reference Field (IGRF) model. While results are typically accurate to 30 minutes of arc, users should be aware that several environmental factors can cause disturbances in the magnetic field.

Distribution Formats
  • HTML Format (Version: 1)
    • File Specification: The Magnetic Field Calculator creates an HTML pop-up window which indicates the declination, inclination, horizontal intensity, northerly component, easterly component, vertical component, and total field at the location queried and reports the annual change for each parameter.
  • XML Format (Version: 1)
    • File Specification: The Magnetic Field Calculator creates an XML document which indicates the declination, inclination, horizontal intensity, northerly component, easterly component, vertical component, and total field at the location queried and reports the annual change for each parameter.
  • CSV Format (Version: 1)
    • File Specification: The Magnetic Field Calculator creates an Comma Seperated Variable (CSV) file which indicates the declination, inclination, horizontal intensity, northerly component, easterly component, vertical component, and total field at the location queried and reports the annual change for each parameter.

Processing Steps
  • 2015-04-22T00:00:00 - NOAA created the National Centers for Environmental Information (NCEI) by merging NOAA's National Climatic Data Center (NCDC), National Geophysical Data Center (NGDC), and National Oceanographic Data Center (NODC), including the National Coastal Data Development Center (NCDDC), per the Consolidated and Further Continuing Appropriations Act, 2015, Public Law 113-235. NCEI launched publicly on April 22, 2015.
