Grades 912. With this comprehensive kit, students build and experiment with 3 different types of electromagnets: coiled wire, metal core, and solenoid. Through 6 activities, students see that an electric current creates a magnetic field and learn how to increase the field's strength by changing the length of wire, number of coils, and amount of electric current. Students learn how electromagnets power everyday devices and get to build a simple motor and even their own working audio speaker.
