NASA monitors the South Atlantic Anomaly, a growing magnetic field disturbance affecting satellites and spacecraft.

Likewise, a wire passing through a magnetic field creates an electric current within the wire. This is the basic principle that allows electric motors and generators to operate. In the Earth (see ...

Earth’s magnetic north pole is on the move—and in surprising ways. With the release of the World Magnetic Model 2025, ...

David Bressan is a geologist who covers curiosities about Earth. Without its magnetic field, life on Earth would not be possible since this shields us from harmful cosmic radiation and charged ...

Earth's magnetic field acts like a protective shield around the planet, repelling and trapping charged particles from the Sun ...

But the changes are necessary to keep navigational systems functioning and to make better future predictions about Earth's magnetic field. Earth's main magnetic field is generated in the planet's ...

revealing the latest official predicted placement of Earth's magnetic fields. This version will remain valid until late 2029, during which time we can expect to see the magnetic north pole slowly ...

From there, the other directions can be figured out. Without the Earth’s magnetic field, this useful phenomenon would not occur. Whilst the geographical and magnetic north poles aren’t always ...

Would a dramatic change in the Earth's magnetic field affect creatures that rely on it during migration? Late on a January night in 1993 I found myself on a beach on the Pacific coast of Costa ...

How does the Earth generate its magnetic field? While the basic mechanisms seem to be understood, many details remain unresolved. A team of researchers from the Center for Advanced Systems ...

By studying robins, scientists have found clues to how birds sense the Earth's magnetic field. Just as you might reach for a magnetic compass to find which way is north or south, birds are thought ...

"It's a really tiny magnetic field. It's about 2-2.5 nanotesla at satellite altitude, which is about 20,000 times weaker than the Earth's global magnetic field," Nils Olsen, from the Technical ...
