Magnetic Field Viewing Kit with Steel Filings by Dowling Magnets

About this item

• 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).
• Explore the basics of magnetism (attraction, repulsion, polarity, and more). US safety tested for ages 8+/grades 3+.
• 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.
• Observe the invisible lines of force of a magnet and interact with it manually! Position the magnet beneath the dish. Carefully agitate the dish. Tilt the dish to one side to ensure the excess filings move away from the magnet. Observe how specific regions of the magnet pull in more filings. These regions designate the poles of the magnet. How do the attraction areas of the disc magnet compare to those of the bar magnet? Where are the poles of the disc magnet located? Where are the poles of the bar magnet located? Gaps in the filing pattern inside the dish indicate the boundaries between the magnet's poles.
