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.
