Earth’s inner core began to solidify sometime after 565 million years ago — just in time to prevent the collapse of the planet’s magnetic field, a study finds.

Small magnetic waves have been discovered at Earth's core, with each oscillation working on a seven year cycle. Earth's magnetic field is generated by electric currents generated by the movement ...

Earth's magnetic field has reversed periodically throughout the planet's history. Now, we're a little closer to understanding why.

ANU geophysicist Professor Hrvoje Tkalčić says that the dynamics of Earth's magnetic field is an area of strong interest in the scientific community. A doughnut-shaped region thousands of ...

The oldest firm age yet for Earth's magnetic field suggests that it developed before a solid planetary core, 3.7 billion years ago.

The magnetic field is thought to arise according to the so-called geodynamo model: the molten core’s movement gives rise to electric currents that in turn produce the magnetism of Earth.

This visualization of Earth's core shows how turbulent waves (shown in red and blue) twist up the planet's magnetic field lines (orange) into pockets of intense activity.

Movements of the Earth's magnetic field are triggered by rising blobs of molten material within the planet's core, a new model suggests. These 'jerks', which happen every 6 to 12 years, have been ...

A doughnut-shaped region thousands of kilometers beneath our feet within Earth's liquid core has been discovered, providing new clues about the dynamics of our planet's magnetic field.
