The Magical World of Magnets Discover invisible forces that move objects without touching! by , Ms Rowida Bayoumi Non-Contact Force Invisible Power Forces that work without touching. Gravity Pulls objects towards Earth. Electricity Attracts or repels charged particles. What is Magnetism? 1 Invisible Force 2 Natural Magnets 3 Man-made Magnets Magnetism pulls or Some rocks have We can create magnets pushes certain materials. magnetic properties. from special metals. Magnetic Materials Attracted to Magnets Not Attracted Iron Plastic Nickel Wood Cobalt Glass Magnetic Poles North and South Opposites Attract Same Poles Repel Every magnet has two poles. North and south poles pull North-north or south-south together. push apart. Magnetic Fields 1 Invisible Lines Magnetic force extends around the magnet. 2 Field Strength Stronger near the magnet, weaker farther away. 3 Visualization Iron filings show the field pattern. Earth's Magnetic Field Giant Magnet Earth acts like a huge bar magnet. Compass Needle Points to Earth's magnetic north. Animal Navigation Some animals use Earth's field to navigate. Fun with Magnets Magnetic Painting Create art using iron filings and magnets. Levitating Pencil Make a pencil float using ring magnets. Magnetic Maze Guide a paperclip through a maze with magnets. Magnetic Slime Make slime that responds to magnetic fields.
