"A strong magnetic field is very important for life on a planet." ...

Geophysicists have modeled how Earth’s magnetic field could form even when its core was fully liquid. By removing the effects of viscosity in their simulation, they revealed a self-sustaining dynamo ...

Earth is fortunate in having a magnetic field: it protects the planet and its life from harmful cosmic radiation. Other planets in our solar system—such as Mars—are constantly bombarded by charged ...

A weak spot in the Earth's magnetic field is growing over the South Atlantic Ocean, according to more than a decade's worth of satellite data collected by scientists. The magnetic field surrounding ...

Our planet’s magnetosphere has seen dramatic shifts across its history—even total reversals—but this recent wrinkle doesn’t pose a threat to life Earth’s magnetic field surrounds the planet, with ...

The magnetic North Pole is on a journey toward Russia in a way that has not been seen before. The British Geological Survey (BGS) works with the U.S. National Oceanic and Atmospheric Administration to ...

Using 11 years of magnetic field measurements from the European Space Agency's Swarm satellite constellation, scientists have discovered that the weak region in Earth's magnetic field over the South ...
