DESCRIPTION
Sprinkle these iron filings on a piece of paper and then move magnets underneath to create magnetic field patterns. For less mess, sprinkle iron filings into a clear plastic page protector or into a plastic petri dish. You'll get 12 ounces of fine mesh iron filings in an easy-to-dispense jar that's just right for a classroom or large group.
