Long-term satellite measurements show that Earth’s magnetic field is changing faster and more unevenly than expected, driven ...

Our planet's invisible shield is changing in ways that scientists are only beginning to understand. Over the past two hundred years, Earth's magnetic field has weakened by around nine percent on a ...

In the blink of an eye in geological time, Canada has lost one north pole but gained another, a new and different claim to be ...

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 ...

The movement of the magnetic North Pole is the result of the Earth having an active core. The inner core, starting about 3,200 miles below your feet, is solid and under such immense pressure that it ...

Earth’s magnetic north pole has shifted toward Russia, prompting updates to GPS and navigation systems worldwide. Scientists track this invisible movement to keep technology accurate.

A magnetometer is a device that measures magnetism: the direction, strength, or relative change of a magnetic field at a ...

Geophysicists from ETH Zurich and SUSTech, China, have demonstrated the dynamo effect of the Earth’s core in a model in which viscosity has no influence, as is the correct physical regime for the ...
