The World Magnetic Model calculates the intensity and direction of the Earth's magnetic field on a specific date-time, geodetic altitude, latitude, and longitude. It is relied upon throughout the world for navigation, mineral exploration, atmospheric and space science, and is installed on billions of devices.

A comprehensive description of the World Magnetic Model, including its limitations, can be found here.

We provide a RESTful API to access the out-of-cycle World Magnetic Model (WMM2015v2) valid for years 2015.0 - 2020.0 and WMM2020 valid for years 2020.0 - 2025.0
