The Earth's Magnetism

Earth’s magnetism was understood with a dipole model by 1600. Magnetic declination became an object of worldwide observation due to its importance in navigation, which continues today. Electromagnetic field theory began by 1821, and the Earth’s field was eventually understood in terms of a dynamo. The dynamo and declination ultimately supported the plate tectonics revolution in geology. The Earth’s magnetic poles migrate and reverse unpredictably. The magnetosphere normally shelters Earth from space weather, but there is a serious hazard to infrastructure from solar coronal mass ejections.
