Abstract

This is a simple demonstration to show what electromagnetic induction is. A Citizens Band radio is used as a radio-frequency generator. A fluorescent tube glows when it is placed right next to the antenna of the radio. The "Star Wars" glow not only draws the students' attention but also demonstrates how easy it is to transfer energy from radio-frequency to atomic species by induction. Some questions are suggested which may help the students to relate the observations to the inductively coupled plasma instrumentation. The phenomenon of electromagnetic induction is no longer a mystery, and the students are eager to learn more about this advanced analytical technique.
