Magnet science project ideas include magnetic slime, water flow through magnetic fields and magnetic money. Test floating magnets as an advanced science project for teens.
Create magnetic slime with borax, school glue and iron fillings. Test the water flow through magnetic fields by checking the flow out of a burette, first into an empty container and then with magnets. Use a very strong Neodymium magnet to test the magnetic ink in the edge of a dollar bill by folding the bill in half. Test floating magnets using liquid nitrogen, a magnet and a yttrium-based conductor. Use safety gloves and goggles for floating magnet experiments.
