Figure 1: Equatorial and meridional cross-sections of the axial component of the vorticity, ω z. Figure 2: Sheet plumes observed in experiment and simulation. By observing the plume pattern as a movie ...

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 has introduced a simulation method that promises ...

The Earth has a shell-like structure. It is divided into a core (inner and outer core), a mantle (lower and upper mantle, separated by a transition zone), and the earth's crust. The Earth’s magnetic ...
