Researchers have spotted interesting changes in the South Atlantic Anomaly, which is a region of Earth’s magnetic field that has a large dent. The area of weak magnetism appears to be splitting ...

A rare geological event occurs every 300,000 years or so: the Earth’s magnetic poles flip. The magnetic poles are the two ends of the magnetosphere, which surrounds the Earth like a giant, invisible ...

Today the magnetic field is more or less aligned with Earth’s rotational axis (each pole lies about 11 degrees off from the geographic poles). But it isn’t fixed in place — the complex motions of the ...

The oldest firm age yet for Earth's magnetic field suggests that it developed before a solid planetary core, 3.7 billion years ago. When you purchase through links on our site, we may earn an ...

Geologic records reveal that magnetic field strength and oxygen levels rise and fall together, implying deep-Earth processes ...

How does a compass work in space? From the moon to Venus, here's how a compass would work beyond Earth's magnetic field.

Earth’s magnetic field was once 30 times weaker than it is today. This change may have played a pivotal role in the blossoming of complex life, new research found.

The magnetic field, thought to be generated by the movements of Earth's molten core, protects Earth from the sun. It does not, however, cause climate change when it shifts. Illustration by MARK ...

So-called cracks in the Earth's magnetic field have led to spectacular aurora light shows being seen in the skies, despite there not having been a solar storm to generate them.. According to ...

Unlike the geographic North Pole, which marks a fixed location, the magnetic north pole’s position is determined by Earth’s magnetic field, which is in constant motion.
