It Looks Like Magic, But It's Physics: Plasma Globes!

What the video shows is an inductively coupled plasma contained inside a sealed glass globe filled primarily with krypton gas, with smaller amounts of xenon and argon. The plasma is generated by a high power electromagnetic field rather than direct electrical contact, forming a bright plasma toroid that hugs the coil. This configuration is a much higher power recreation of the classic plasma toroid experiment, operating at roughly ten times the typical power, which is why the plasma ring is tigh
