Magnetic Field Viewer 25/30/50mm Testing Card for DIY Crafts

Azabooti presents the Magnetic Field Viewer for DIY crafts, a compact card to visualize magnetic fields. See color coded patterns directly on 25x25, 30x30, or 50x50 mm cards.

See magnetic fields come to life with one simple card

You don’t have to imagine invisible forces to study magnetism. Our Magnetic Field Viewer turns unseen magnetic patterns into visible, color coded images you can observe directly. This compact, easy-to-use film card helps you explore field distributions, identify poles, and demonstrate magnetic concepts with clarity and impact. It’s a practical tool for students, hobbyists, teachers, and professionals who want a hands-on way to visualize magnetism without electronics.

What you get
