Abstract

The main part of the geomagnetic field is generated by self-induction in the Earth’s molten core. The geodynamo mechanism is not yet fully understood as an M.H.D. problem even though we have many constraints coming from observations, as well as from geophysical and geo-chemical theories. This Earth’s science problem combines many of the difficulties we face in physics (turbulence), in applied mathematics (nonlinear equations, boundary layers), in technology/engineering (liquid metal experiments) and in computing sciences (numerical modelling).
