Magnetohydrodynamics (MHD) is the study of the flow of electrically conducting fluids in the presence of magnetic fields. It has significant applications in technology and in the study of planets, stars, and galaxies. Here the main focus will be on its role in explaining the origin and properties of the geomagnetic field.

The interaction between fluid flow and magnetic field defines the subject of MHD and explains much of its fascination (and complexity). The magnetic field B influences the fluid motion V through the Lorentz force, Open image in new window
