CMS MAGNETICS 12" x 12" Green Magnetic Field Viewing Film, Fun!

Product Description

Encased within green film are millions of magnetic particles suspended in oil. The viewing film changes shade when a magnetic field is applied. It turns dark when the field lines are perpendicular to the surface, and it turns light when the field lines are horizontal, i.e., across the surface. If a magnet is placed under the film with one of the poles facing the film, , a dark outline of the magnet will appear. The film is highly flexible and can be easily wrapped around objects.

Features

• SIZE & FILM TYPE - 12x12 Inch single color Green Film.
• GREEN FILM - Metal nano-particles suspended in an oil that tilts in reaction to a magnetic field in close proximity to the film. Light bounces off the tilt of these nano-particles towards your eye to review the hidden magnetic patterns of that magnet. Different magnet shapes will give off different magnetic field patterns. This film is green but will showcase different shading of the green based on the tilt of the nano-particle positions.
• 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.
