Green Magnetic Field Viewing Film

Wish you had the power to see magnetic fields like a superhero or a bird can? This cool new Green Magnetic Field Viewing Film is a fascinating sheet of green film that encases millions of nano-sized magnetic particles suspended in oil that change shades when placed next to a magnetic fields. Simply place the flexible viewing film over a magnet, even a hidden one, and it instantly reveals it by changing either to a dark shade when the magnetic field lines are perpendicular to the surface, a light shade when the field lines are horizontal, or a dark outline when one of the poles is facing the film. While originally designed as a tool for professional engineers and researchers, it also makes a super fun learning toy for students or anyone who loves science. Check out this video to see it in action. Cool huh?
