About This

• Includes 2 magnets (.75 inch disc magnet and 1 inch bar magnet) and 1 filing-filled tray measuring 3.44 inches in diameter. The small bar magnet has color coded poles (red north and blue south).
• Features scratch-resistant plastic, rubber-coated magnets, and clean steel flings for clear viewing! Filings are sealed inside a mess-free, transparent viewing tray made of special scratch-resistant plastic that stands up to classroom use. Steel filings (cleaner than iron filings) ensure cloud-free viewing. Magnets are rubber-coated to prevent scratching of the viewing tray.
• View a magnet’s invisible lines of force and manipulate it with our own hands! Place a magnet under the dish. Gently shake the dish. Tip the dish to one side, so the extra flings inside fall away from the magnet. Notice how certain areas of the magnet attract more filings. Those areas are the magnet’s poles. How do the areas of attraction of the disc magnet differ from those of the bar magnet? Where are the disc magnet’s poles? Where are the bar magnet’s poles? “Breaks” in the pattern of the filings inside the dish indicate the separations between the poles of the magnet.
• Explore the basics of magnetism (attraction, repulsion, polarity, and more). US safety tested for ages 8+/grades 3+.
