Magnetic Field Grid Calculator

Metadata Updated: January 30, 2017

The Magnetic Field Properties Calculator will computes the estimated values of Earth's magnetic field(declination, inclination, vertical component, northerly component, easterly component, horizontal intensity, or total intensity), for a specific location, elevation and date or range of dates based on the current International Geomagnetic Reference Field (IGRF). The calculated result is a grid that contains the calculated component and the annual change of the component over the geographical area specified. WDeclination 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.
