Just slide the long magnet into the tube and watch the iron filings stand at attention. The long magnet is actually a powerful cow magnet used to protect dairy cows from ingesting pieces of scrap metal. The iron filings are housed in a plastic tube that allows students to see the invisible magnetic forces while keeping you mess-free in the process. Amaze your audience as you watch the magnet draw the iron filings into patterns around the magnet's north and south poles.
