Ferrofluid on the track of a Meatgrinder. Strange Matter: Photographs. Magnetohydrodynamics. The sun is an MHD system that is not well understood. The fundamental concept behind MHD is that magnetic fields can induce currents in a moving conductive fluid, which in turn creates forces on the fluid and also changes the magnetic field itself. The set of equations which describe MHD are a combination of the Navier-Stokes equations of fluid dynamics and Maxwell's equations of electromagnetism.

These differential equations have to be solved simultaneously, either analytically or numerically. History[edit] The first recorded use of the word magnetohydrodynamics is by Hannes Alfvén in 1942: "At last some remarks are made about the transfer of momentum from the Sun to the planets, which is fundamental to the theory (§11). The ebbing salty water flowing past London's Waterloo Bridge interacts with the Earth's magnetic field to produce a potential difference between the two river-banks.
