In this experiment, an electric arc is struck between two electrodes positioned inside a ring magnet, and the magnetic field bends the ionized plasma into a rotating, glowing vortex instead of letting it arc in a straight line. It's a small-scale demonstration of magnetohydrodynamics, the same branch of physics that governs how magnetic fields confine and shape plasma in fusion reactors and stars. Built from little more than magnets, electrodes, and a wooden base, it's a striking reminder of how much real physics you can observe with a simple homemade setup.
