Science and the World Magnetism Activity Engagement for Electromagnetic Force

Background Any physics textbook The New Way Things Work CR-ROM from Dorling Kindersley, New York. How Stuff Works website,

Materials Wire (both coated and uncoated) –Copper –Nickel Nails (2 to 3 inch long) various types –iron –galvanized D cell alkaline batteries Bar magnet with marked north and south poles Small screws or paper clips

Activity Highlights First, discuss magnets to see what students already know and so they can see what they have questions about In groups of two, allow students to build electromagnets with as little coaching from teacher or fellow as possible Try to pick up as much as possible

Activity Highlights (2) Compare electromagnets to permanent magnet Try to use new materials to build better magnets Compete with other groups to see what the best materials are
