Swarm shows rate of change
The animation shows changes in the rate at which Earth’s magnetic field strengthened and weakened between 2000 and 2015. Regions where changes in the field have slowed are shown in blue while red shows where changes speeded up. For example, in 2015 changes in the field have slowed near South Africa but changes got faster over Asia. This map has been compiled using data from ESA’s Swarm mission.
