A visualization of the Levitating Dipole Experiment at MIT's Plasma Science Fusion Center. In this animation, the superconducting coil (green) has been magnetically levitated. The animation shows the affects of varying the current in two "Helmholtz" coils exterior to the containment vessel (gold loops). As the current in these coils is varied, the magnetic field in the interior of the vessel is changed, causing magnetic field lines that were previously "closed" (not touching the walls of the containment vessel at any point) to become "open" (touching the walls at some point). This allows the experimenters to explore the affects of "dumping" parts of the confined plasma by allowing the field lines to touch the walls.
