Make invisible magnetic fields instantly visible
The Magnetic Field Viewer Film is a flexible, reusable 4" × 4" sheet that makes the invisible structure of magnetic fields visible the moment you place it over any magnet. Millions of suspended nickel nanoparticles align themselves along field lines, producing a clear pattern of light and dark that reveals pole locations, field strength, and field shape — no equipment, no setup, no prep.
Why Teachers Love It
- Instant, No-Prep Visualization – Place the film directly on or near a magnet and field lines appear immediately, making abstract concepts concrete in seconds.
- Reusable and Self-Resetting – The film recovers on its own after each use, so it holds up to repeated student handling without consumable cost.
- Works with Any Magnet – Compatible with bar, ring, horseshoe, ceramic, and neodymium magnets; also reveals hidden magnets in everyday objects for engaging discovery activities.
Product Details
What You Can Teach with the Magnetic Field Viewer Film
Grades 3–5 (Upper Elementary)
- Magnetic poles exist and have distinct locations — the film shows them clearly
- Magnetic fields are invisible forces that spread through space
- Magnets attract and repel — observe the difference in field patterns
- Hidden magnets in everyday objects (phone speakers, refrigerator door seals)
Grades 6–8 (Middle School)
- Field line density as a visual representation of field strength
- Comparing field shapes: bar vs. ring vs. horseshoe magnets
- Introduction to electromagnetic fields and how poles interact
- Connecting observations to compass needle behavior and Earth's magnetic field
High School / AP Physics
- Qualitative analysis of field geometry and flux density
- Comparing permanent magnets with electromagnet field patterns
- Supporting discussions of Faraday's law and magnetic flux
- Using physical models to develop and test explanations of field behavior
