This is a test for all the world to see and understand. Lots of interesting text will follow, but for now, we'll just stick to what we've got.
This page contains lots of information of Ferrofluids. Ferrofluids are very interesting things. They have an affinity towards magnets, as demonstrated by the images to the right.
When a magnet is brought near a ferrofluid, the liquid will actually move. If the magnetic field is oscillatory, then the magnetic field will drive the ferrofluid at the same frequency.
Simple dynamic systems have a natural frequency. If they are driven at that frequency, then some kind of usual behavour occures. If a crystal wine glass is driven (by someone singing) at the natural frequency, then the glass shatters. If a fluid in a vessel is driven at its natural frequency, then splashing occures.
Splashing is when the top of a wave crest splits off from the rest of the wave and is ejected upwards.
Ferrofluids are important to plasma research because the surface of a magnetically confined plasma (such as the plasmas various Tokamak reactors) can be modelled by Ferrofluids. The surface tension of a ferrofluid corresponds to the magnetic fields confining a plasma, and the bulk motion of the fluid corresponds to large timescale response of plasmas.
The magnetically confined plasma equivilent of splashing are disruptions. Disruptions are event where the plasma escapes from the containing magnetic field, causing damage to the reactor vessel and, in a full scale reactor, preventing continous supply of power.
