Knowing what the magnetic field did in the past can help us predict its future. And some studies suggest our planet's magnetic field is weakening over time. The magnetic field shields us from deadly ...

The South Atlantic Anomaly (SAA), a known region of Earth’s magnetic field weakness, has been under the observation of the European Space Agency’s Swarm mission for over a decade. New findings reveal ...

Up until the 1990s, scientists have known that the Earth’s magnetic north was drifting at a rate of up to about 9 miles (15 kilometers) a year. Now, however, the drift of Earth’s magnetic north pole ...

The weak spot in Earth’s magnetic field, a region over the South Atlantic where the field’s strength is significantly reduced compared to its surrounding area, has grown by an area nearly the size of ...

Earth's magnetic field acts as a vital shield against radiation arriving from space, but it is not constant. A new international study has examined how a reduction of the magnetic field similar to the ...

During a brief but dramatic chapter in Earth's history about 41,000 years ago, the planet's magnetic field nearly collapsed. What followed was a cascade of environmental and biological changes that ...
