Plasma globe - Wikipedia
A plasma ball, plasma globe, or plasma lamp is a clear glass container filled with noble gases, usually a mixture of neon, krypton, and xenon, that has a high-voltage electrode in the center of the container.
Plasma ball | University of Oxford Department of Physics
The graceful purple arcs of plasma dancing in a plasma ball are created by a large alternating voltage at its centre, and that alternating voltage creates an electromagnetic field with which we can light a fluorescent tube.
Plasma Ball Experiments – The Wonders of Physics – UW–Madison
The plasma ball is a miniature Tesla coil. Inside the ball is a coil of wires that have electrons going through them oscillating at a very high frequency. This shakes the atoms around the wires so hard that their electrons start to fall off!
Plasma Ball and Fluorescent Light Experiment - ThoughtCo
2020年2月5日 · You can perform an interesting science experiment using a plasma ball and a fluorescent light bulb. The fluorescent bulb will light up as you bring it near the plasma ball. Control the light using your hand, so only part of it is illuminated. Here is …

2012年6月17日 · If you touch the plasma ball, all of the electrons will go through you to the ground. You see only one big spark inside the ball where you put your hand. If you touch it long enough, you get filled with electrons and can light up a light bulb!
How Does A Plasma Ball Work? - Sciencing
2017年4月24日 · A plasma ball is essentially a miniature Tesla coil channeling an alternating voltage of about 2-5 kilovolts at a frequency of about 30 Hertz, enclosed within a glass ball containing an inert gas such as neon or argon.
How does a plasma ball work? – Physics tutor
2019年4月26日 · Currents flow through the plasma as arcs of colourful light. The light is caused by excitations of atoms that then shed further electrons. The process goes on and on until it is switched off. If you touch the outside of the dome the current actually flows harmlessly through your body into the ground.
Plasma Ball Colors | Physics Van | Illinois
In reference to the plasma ball, why does the electricity in the globe change colour, from blue in the centre to pink towards the glass? Plasma balls work by electrical discharges through low-pressure gases.
