Using energy analysis and some tinkering students hand wind speakers to play music from a phone. This acts as a phenomenon to engage students in the exploration of electromagnetism. At this point, they have created a motor, which utilizes electric current to...
1. Through hands-on exploration, create a working speaker for a cellphone. 2. Use the creation of a speaker to observe as a model for the process of generating electrical current in a simple generator/motor.
