Encased within the green film are millions of magnetic particles suspended in oil. A magnet will attract the particles to the areas where the magnet is the strongest - at its poles. The poles appear dark green. Multiple pole magnets such as those on business card magnets will display interesting patterns, such as the example pictured below.
The film is highly flexible and can wrapped around objects. The film can also be laminated. It is NOT currently laminated.Also available in 12 x 12 inch sheets!

Please Note:The viewer film come from the factory as a uniform green. However, once the film is exposed to a magnetic field, black lines or dark areas will remain in the film, even after the magnetic field is removed. This is normal behavior for the film. The film can be re-used over and over again and will continue to show the magnetic field of sources strong enough to coerce the the suspended iron particles in the film.There is no practical way to reset the film to the uniform green from the time of manufacture. Exposing the film to a very large magnet or magnetic field can bring the film fairly close to an even color. Customers have reported that magnetic tape de-gaussers, used to erase audio tape, work fairly well at restoring the original green color to the film.NEED SOME MAGNETS CLICK HERE
