Description

This map layer shows lines of equal annual change (secular variation) in the inclination of the Earth's magnetic field, derived from the International Geomagnetic Reference Field (IGRF) for the epoch 2010.0. Magnetic inclination is the angle between the magnetic field vector and the horizontal plane. The change is measured in arc minutes per year.
