Files Associated with this Activity:

Through a series of goal-oriented activities and research, students will build physical models that demonstrate the interactions between magnetism and magnetic fields as well as interactions between magnetism and electric fields. Students will be challenged to engineer devices that: change a magnetic field using electricity, creating a magnet using electricity, and inducing a changing magnetic field using a magnet. This lesson is suitable as an introduction to electromagnetism for various purposes especially for electricity generation (wave and tidal power, hydropower, wind power, and fossil fuel electricity generation).
