How to calculate the magnetic field for a location?
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.
Which is the most recent geomagnetic reference model?
Declination is calculated using the most recent World Magnetic Model (WMM) or the International Geomagnetic Reference Field (IGRF) model. For 1590 to 1900 the calculator is based on the gufm1 model. A smooth transition from gufm1 to IGRF was imposed from 1890 to 1900.

How to calculate the earth’s magnetic field for one day?
If you want all seven magnetic field components for a single day or range of years from 1900-present, please visit our Magnetic Field Calculator. Please read the instructions below before using this calculator.
Is the International geomagnetic reference field ( IGRF ) valid?
The International Geomagnetic Reference Field (IGRF) is produced by the voluntary research of the scientific community under the banner of the International Association of Geomagnetism and Aeronomy (IAGA). The IGRF is retrospectively updated, and valid for the years 1900-2024. IGRF model: https://www.ngdc.noaa.gov/IAGA/vmod/igrf.html.
How to calculate the declination of the magnetic field?
U.S. Historic Declination calculator This calculator uses the US declination models to compute declination only for the conterminous US from 1750 – present. Due to differences in data availability (recorded observations of the magnetic field), the western part of the US may not have values until the early 1800’s.
