Magnetic Field Viewing Kit for Dowling Magnets - with Steel Filings

About this item

• 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 unseen lines of force of a magnet and interact with it physically! Position a magnet beneath the container. Shake the container gently. Tilt the container to one side to remove excess filings from the magnet. See how specific regions of the magnet draw in more filings. These regions represent the poles of the magnet. How do the attraction areas of the disc magnet compare to those of the bar magnet? What are the locations of the disc magnet's poles? Where are the poles of the bar magnet located? Gaps in the filing arrangement inside the container indicate the boundaries between the magnet's poles.
• 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).
