Declination Calculator |
|
Declination is calculated using the current International Geomagnetic Reference Field
(IGRF) model. 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. |
