Iron Filings for Magnetic Field Activities, 12 oz Jars, Pack of 3

Make invisible magnetic fields easier to see with Iron Filings for Magnetic Field Activities, 12 oz Jars, Pack of 3. Iron filings are a classic science material for demonstrating field lines around bar magnets, horseshoe magnets, ring magnets, and other magnetic objects. Sprinkle a small amount onto paper or a protected tray, then move a magnet underneath to observe how the filings align with the magnetic field. The 12 oz jar format is practical for repeated demonstrations, lab groups, and classroom science centers. Use with proper supervision and cleanup practices for hands-on lessons about magnetic force, field patterns, attraction, and polarity.
