Originally appearing in our demonstration catalog as J3-23 and now as the updated K8-46, the Faraday Cage and Radio Waves demonstration is a popular way of showing how a conductive surface interferes with the passage of electric fields, and thus can prevent the transmission of electromagnetic waves.

 

Now, our own Don Lynch has created an animation of the physics behind this demonstration; check it out below! 

 The Lecture-Demonstration Facility is introducing a series of teaching aid animations of popular demonstrations; watch for more coming soon!
