ELECTROMAGNETISM LESSON: Build a Speaker |
|
| Basic electromagnetism is explained and experienced in this fun three-hour class for 10-30 students. Students learn and use the concepts of Ohm's Law through electromagnetic induction demonstrations and activities. Each student builds a loudspeaker using wire and a magnet. Older students enjoy the challenge of constructing a functional electric guitar based on these same principles. | ||
