Magnetic anomaly interpretation and geophysical modeling represent pivotal approaches in understanding subsurface geological structures by analysing local variations in the Earth’s magnetic field.

Recently the MagQuest competition on improving the measuring of the Earth’s magnetic field announced that the contestants in ...

The Earth's liquid molten outer core, composed mostly of iron and nickel, exerts an electromagnetic field extending from the north and south pole that protects the planet from harmful solar particle ...

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 ...

The updated version of the World Magnetic Model was released on Dec. 17, with a new prediction of how the magnetic north pole will shift over the next five years. Here's why it was changed. When you ...
