Figure from experiment 26 from Physics Explorations and Projects


In this project, students apply the principles of electromagnetic interactions to build a speaker. The basic principle is to have a solenoid-style coil of wire attached to a surface that is able to vibrate along the axis of the coil of wire, and a fixed magnet inside the coil of wire. The coil should be attached to some object or surface which will move as the coil vibrates, displacing air and creating sound waves. There are many ways to make this work. Allow students to be creative.

Learning Outcomes

Build a speaker by taking advantage of the interaction between electric current and magnetic fields.
