About This

• Distinct Green Magnetic Sensing Film: Built with micro-encapsulated magnetic sensitive particles, instantly shows clear magnetic flux line patterns when laid on any magnetic for source for intuitive observation.
• Multiple Optional for mini: Available in 25×35mm, 30×50mm and 40×45mm compact dimensions, suitable for small magnet samples, tiny electronic magnetic parts and narrow test spaces.
• Ultra-Flexible Portable Design: Lightweight thin film can be bent to fit curved surfaces, easy to store in teaching kits or tool bags and carry for field inspection.
• Wide for educational & Industrial Application: Perfect for school physics teaching, laboratory magnet research, factory magnet quality testing, product magnetic structure analysis and science hobby projects.
• Simple Operation & Reusable: No power supply required, just place the film on magnetic surfaces to view invisible magnetic fields; automatically recovers for repeated long-term use.
