NOAA scientists have spent decades tracking how magnetic north wanders, but recent modeling shows a pole moving in ways ...

Learn how some of Earth’s magnetic field flips last longer than others, weakening our defenses against cosmic radiation.

Earth's magnetic field is generated by the churn of its liquid nickel-iron outer core, but it is not a constant feature. Every so often, the magnetic north and south poles swap places in what are ...

3D rendering of Planet Earth's magnetic field. Earth is unique in the solar system for a number of reasons: It's the only planet with a breathable oxygen atmosphere, it's covered in liquid water and ...

Earth's magnetic poles flip in a process called a geomagnetic reversal. The planet's magnetic field is generated by chaotic ...

Deep beneath the ocean floor, ancient sediments hint that Earth’s magnetic field sometimes changed far more slowly than expected.

By comparison, the magnetic north pole is the northernmost convergence point in Earth’s magnetic field, also known as the magnetosphere. Generated by the churning molten metals in Earth’s core, the ...

How does a magnetic compass work? Well, it’s all down to basic physics and human ingenuity. The key component of a standard baseplate compass is its magnetized needle, which is allowed to spin freely ...

The magnetic north pole just isn’t where it used to be. Ever since the British polar explorer James Clark Ross first identified it on the Boothia Peninsula in Canada’s Nunavut territory in 1831, ...
