Permanent Magnet Pattern Detector Sheet

Permanent Magnet Pattern Detector Sheet Magfilm Neodymium Magnet Feild Viewer Film, Green  Magnetic Feild Viewing Film, High Definition Square Magnetic Viewing Paper, Magnetic Feild Detection Display, MagFilm See Magnetic Field with This Magic Film to Learn Magnetism. Applicable for Permanent Magnets

Permanent Magnet Pattern Detector Sheet – Magnetic Field Viewer Film is highly flexible and can wrapped arround objects. The film can also be laminated. It is NOT currently laminated. 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. Keep away from children, pacemakers and other implants. Handle with care. Our magnets are made for the adult inventor, manufacturer, researcher, DIYer, problem solver, etc.

This same film is used by professionals, like engineers, developers and researchers to find out the magnetic field distribution when a group of magnets are involved. It is also used in the fabrication industry to image the internal defect of a steel part combined with an X-Ray machine. Encased within the green film are millions of nano size magnet particles which can turn freely when close to a steel object or a permanent magnet. When the magnet particles change their orientations, the reflection rate to the light will also change so to show the magnetic field beneath it. This is why the film will change shades when a magnetic field is applied. The film turns darker when the magnetic field lines are perpendicular to the surface, and lighter when the field lines are horizontal, i.e., across the surface. If one pole is placed under it, it will show the magnet as a dark area with a lighter outline. If both poles are placed under the film, the areas close to the two poles are dark but the border of the two poles will show up as light line, so you can tell the pole orientations. Our pictures show the two same dimension magnets but magnetized differently. Also the film is highly flexible and can be easily wrapped around magnetic assemblies. Tips and uses: 1. Place the film close to the magnet to observe the pattern changes so you can identify how the magnet is magnetized and where the magnetic poles are on the magnet. 2. The stronger the magnets, the better the results. We recommend neodymium magnets instead of ceramic magnets. 3. To get the same results of our pictures, be sure to use the same type and same quantities of magnets. 4. The film will not identify north or south poles. Should you need a pole identifier, you can check out our pole detector listings. 5. Do not fold the film since it will leave a permanent wrinkle on it. Magnetic Pattern Viewer
