Magnets attract metallic objects like iron nails, metal clips, coins, and scrap metal due to the strong attractive force between the magnet and these ferromagnetic materials. Magnets do not attract non-metallic objects like leaves on trees, paper boats, pencils, wood, or handshakes that are not affected by magnetic fields. The document provides examples of positive and negative interactions with magnets to define magnetism and distinguish between materials magnets can attract versus those they have no effect on.
