CMS Magnetics 4" x 6" Green Magnetic Viewing Film - Educational and Fun!
Description
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.
Features
Green Micro-Encapsulated Film used to Show Magnetic Field, or Test Cracks on Steel Surfaces
Very Interesting to Actually See the Magnetic Field! It is Flexible so can be Wrapped around the Tested Magnets
Applicable to All kinds of Permanent Magnets, Such as Neodymium, Ceramic, SmCo, AlNiCo and Flexible Magnets. To Expose Magnetic Field, Place Directly on Top of the Magnets
Wonderful Educational Tool for Magnetism
