Toroidal Plasma Generator: an intricate dance of high intensity/high frequency electric and magnetic fields produce a ring of glowing plasma within a glass sphere containing noble gasses at low pressure. This BagleGen device is the latest in high tech kinetic art by creator Zerg Dragonymous of @teslacoilpro. What most amazes me here is how these very complex fields can be produced by circuit of only a few components- the main structure in the base is a cooling fan with a huge heat sink attached
