What you’re seeing isn’t just a cool glow—it’s a plasma vortex being shaped by a magnetic field. Plasma is often called the 4th state of matter: a gas so energized that electrons are stripped from atoms, creating a mix of charged particles (ions + free electrons). Because those particles carry charge, they don’t just drift randomly—they respond to electromagnetic forces. In this small-scale homemade setup: * A high-voltage source ionizes gas → creating plasma * A magnetic field (from coils or permanent magnets) is applied * Charged particles experience the Lorentz force → causing curved motion * The result: a visible vortex structure, where plasma spirals along magnetic field lines This is the same core physics behind: * Fusion research (tokamaks + stellarators) * Solar flares and space plasmas * Aurora patterns in Earth’s magnetosphere Even at a small DIY scale, you’re essentially recreating a simplified version of plasma confinement physics—just with less energy and way more ac...
