Students will design and build electromagnets to explain the following phenomenon: when an electric current moves through a wire, an invisible magnetic force surrounds it. Students will analyze how adding a conductor to the electromagnet will temporarily magnetize the conductor.
The Energy Coalition will send you a roll of insulated wire, a wire cutter, a box of paper clips, compasses, nails, and transformers to bring this lesson to life.
Lesson Objective: Students will plan and carry out an investigation on electromagnetism and explore the cause-and-effect relationship between electricity and magnetism.
Suggested Teaching Time: 75 min
NGSS Standards: 3-PS2-3, 3-PS2-4, 4-PS3-2
