Earth’s Inconstant Magnetic Field Our planet's magnetic field is in a constant state of change, say researchers who are beginning to understand how it behaves and why. Assembled By Ken Mitchell Livermore TOPScience

The movement of Earth's north magnetic pole across the Canadian arctic, 1831—2001.

The Earth's Core

Schematic diagram of Earth's interior. The outer core is the source of the geomagnetic field.

Magnetic stripes around mid-ocean ridges reveal the history of Earth's magnetic field for millions of years. The study of Earth's past magnetism is called paleomagnetism

Supercomputer models of Earth's magnetic field

Earth's Magnetic Field (Magnetosphere)
