Magnetic Field Viewing Kit with Sealed Steel Filings

Observe magnetic field patterns again and again with Magnetic Field Viewing Kit with Sealed Steel Filings. Steel filings are sealed inside a clear, scratch-resistant viewing tray so students can explore field lines without loose filings or messy cleanup. The included magnets allow learners to move, compare, and reposition magnetic forces while watching the filings respond inside the tray. This reusable kit is helpful for demonstrations, STEM centers, small-group investigations, and homeschool science lessons about magnetic fields, poles, attraction, and repulsion. The sealed design keeps the activity contained while giving students a clear visual model of invisible magnetic forces.
