Introduce the Engineering Design Process for problem solving as you explore electricity and magnetism in this electromagnet building exercise. Students examine magnetic field, electrical charge, and the effects of increasing the current on the generation of heat as they compare core materials, core thickness, and number of wraps in coils in these inquiry based investigations. Four engaging activities culminate with teams applying what they learn in a design the strongest electromagnet competition. Includes an extensive instructor manual with lesson plans, background information, reproducible stepwise student instructions, worksheets, complete answer keys, and all materials required for investigation. Available as a single kit (KEM-15-201) for a small group or a class pack (KEM-15-205).
