CMS MAGNETICS – 4×6" Green Magnetic Flux Viewing Film for Revealing Hidden Magnetic Field Patterns in Permanent Magnets for Science Projects, Research and STEM Education in Magnetism

Description

Encased within the green film are millions of paramagnetic particles suspended
in oil. The viewing film will become lighter or darker 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 across the
surface. If a magnet is placed under it, with one of the poles facing the
film, it will show the magnet as dark with a light outline. The film is highly
flexible and can be easily wrapped around objects. This film is sensitive to
steel and may leave images of steel items it is close to, like a pair of
scissors, screw drivers or knives. Images like these do not mean it has been
used or damaged since during the cutting and packing process, it may get close
to steel objects. The images will not damage or alter the magnetic viewing
film.

Features:

• SIZE & FILM TYPE – 4×6 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.
