4 By 4 Inch Magnetic Field Viewing Film With Visual Magnetic Field Lines Display Reusable Magnetic Flux Viewer For Science Projects And Classrooms Magnet Pattern Detector For Hands On Learning And Home Experiments

4x4 Magnetic Field Viewing Film for Visualizing Fields
✔️ Single 100 mm x 100 mm film; reusable magnetic view

This 4x4 inch magnetic field viewing film is a reusable, visual tool that makes magnetic field lines visible using a nickel-iron slurry embedded in a flexible plastic film. The outer frame keeps the film protected during demonstrations, while colors indicate field strength. It's perfect for classrooms, science labs, and home experiments to explore how magnets interact with everyday objects like door latches, speakers, and hidden buckles on bags and devices.

✅ Size: 100 mm x 100 mm (4 x 4 in) viewing area
✅ Material: plastic film with fine nickel-iron magnetic slurry
✅ Outer frame protects and supports the film; reusable and auto-recover
✅ Visual display of magnetic field lines; color coding shows strength
