The fifth lab activity is designed to facilitate the investigation of electromagnetism using solenoids. Students investigate how ferrous material (iron) and magnets interact with an electromagnet. Students draw conclusions based on what occurs when the orientation of the components and/or the battery is changed. Teachers should help students develop the fundamental understandings of electromagnetism so that they can apply this scientific knowledge to future engineering projects. As the five lab activities have built upon each other conceptually, this is an important final experience to promote student understanding.
What are the relationships between solenoids and modern-day inventions?
