Without Earth's magnetic field, migrating animals lose their way and navigation for everything from ships to Boy Scouts is rendered useless. But despite its importance, the process that powers the planet's magnetic field remains a mystery. Ideas abound, but none of them can account for the age of Earth's magnetic field. Now, a new study may have the key to this inconsistency: humble magnesium.

The churning of Earth's molten core generates electrical currents that produce the planet's magnetic field in a process called a dynamo.
