A decade of modelling Earth's core on computers has led to the belief that we understand what produces Earth's magnetic field. More realistic simulations are now shaking that complacency. In a simple ...

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 ...

Researchers are using the Blue Waters supercomputer at NCSA to better understand geomagnetic variations and their underlying mechanisms, so that better forecasting models can be developed. Deep in the ...

The Earth's magnetic field is generated by the complex interplay of convective flows in its liquid outer core, a process commonly referred to as the geodynamo. The dynamics of this magnetic field are ...

Have you ever heard of the geodynamo? Perhaps not, but its presence has certainly had a huge impact on your life. The theory describes how Earth's magnetic field is generated and maintained by ...
