Dowling Magnets Magnetic Field Viewing Kit with Steel Filings

Stays clear! Steel flings 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. Learn how a magnet’s invisible force field works—view it up close and manipulate it with your own hands! Explore the basics of magnetism (attraction, repulsion, polarity, and more). Compare and contrast the magnetic fields of a bar and disc magnet. Includes rubber-coated magnets (.75 inch disc magnet and 1 inch bar magnet)—that won’t cause scratching—and filing-filled tray measuring 3.44 inches in diameter. Ages 8+/Grades 3+
