About This

• Visualize Invisible Forces: Instantly reveals for static magnetic field patterns with high-contrast dark green film, making invisible flux lines clearly visible for study and analysis without needing power.
• Flexible & Design: Encapsulated in a highly flexible protective layer, this viewer conforms to convex or concave surfaces, allowing accurate field mapping on irregular objects and magnets.
• Perfect for Education: An essential STEM tool for physics classrooms and science fairs; it sparks student interest in magnetism through hands-on experiments and visual demonstrations of abstract concepts.
• Compact & Portable: Available in convenient 25x50mm and 50x75mm sizes, this lightweight card fits easily in pockets or lab kits, enabling field research and on-the-go product testing anywhere.
• Versatile Applications: for ideal for quality control, reverse engineering, and certification processes; helps engineers and researchers verify magnetic properties in motors, speakers, and industrial components.
