Make your own smartphone radio (with magnetic field solenoid physics)

A fun little demonstration showing how to send audio signals through the air using electromagnetism. The audio output from a smartphone will generate current in one solenoid and generate B fields that can be detected with a second solenoid. Hook the second solenoid to an amplified speaker and Voila! You just made a radio.

Special thanks to Dr. Jan Chaloupka for this demo tip.
