5G10.11 - Refrigerator Magnets & Floppy Disks
Place the magnets under a piece of paper and shake on a fine coating of the iron filings. The iron filings should line up in rows signifying the rows of North/South poles on the flat magnets. In other words these magnets are made with alternating lines of North and South poles.
