🧲 Unlock the unseen world of magnets—because science looks cooler in color!
This 4x4 inch magnetic field viewing film uses a brownish-yellow plastic embedded with fine nickel nanoparticles to visually display magnetic field lines and intensity through color changes. Housed in a protective frame, it supports a wide range of magnets including SmCo, AlNiCo, and Neodymium. Designed for repeated use with automatic recovery, it’s an ideal tool for scientific projects, education, and magnetic pattern detection.
