CMS MAGNETICS - Wallet Size Olive Magnetic Flux Viewing Card for Revealing Hidden Magnetic Field Patterns in Permanent Magnets for Science Projects, Research and STEM Education in Magnetism

About this item

• SIZE & FILM TYPE - Portable PVC Card of the Olive Film. Same size as an ID or credit card. Olive films can change to a multitude of colors. Very sturdy.
• OLIVE FILM - When a magnet is in close proximity to this film, it creates different colors that look like a heat map based on the magnetic field strength. The film is olive color but may change to yellow, brown, orange, blue, and red. Created with different technology than the green film, it features nano-particles that pushes against each other when being pulled by a magnetic field. Depending on how strongly the nano-particles are pushed together will create different colors.
• SHELF LIFE & LAMINATION - Because these films are created with tiny nano-particles suspended in a liquid, over time the effectiveness of the film may decrease. You can increase this shelf life by having your film laminated to prevent leakage, scratches, and other damages to the film.
• REUSE, RESET - Both films are reusable, but the olive film will have a much longer shelf life than the green film. The olive film automatically resets itself, while the green film may need to be reset by quickly swiping a magnet parallel to the film several times. These products are offered in various sizes that best suit your needs. We also have a portable wallet size pvc card of the olive film. The films can be laminated to increase the life of the film and protect it from bending and damage.
• APPLICATIONS & GIFTING - These films have a multitude of creative applications. They are one of the best STEM educational activities to introduce students to the science and magic of magnetism. They're great for science projects and serve as a teaching tool for teachers in the classrooms. They also make great gifts for any age and gender. The recipients will spend countless hours having fun exploring and revealing hidden invisible natural forces they never knew existed. Give the gift of magic.
