Trusted by professionals and perfect for educational or executive toy use, it flexibly wraps around magnets to reveal pole orientations and field distributions with striking clarity. ## 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. Keywords: refrigerator magnet toy, automotive magnets, inch magnets, Review: Amusant - Pratique et ludique pour montrer les champs magnétiques. Review: Great novelty item - Not useful for daily things, but great for science experiments and entertainment. Probably the most useful thing about it is that it is basically 'x-ray vision' for the eddy current experiment where you drop a high-power cylinder magnet down an aluminum or copper tube and it drops very slowly. With this, you can 'see' the magnet through the tube as it falls. It's also fun to investigate refrigerator magnets and multi-magnet cubes, etc. With this little sheet, I accidentally discovered that putting my rare-earth block magnet on my fridge magnet made an obvious area where the NdFeB permanently overrode the poor little fridge magnet's field forever! :O It didn't stand a chance. "What can ferrite do against such reckless Teslas?" --fridge magnet, 2019-2019 Update: 2022 and mine still works great, although I haven't used it much. Surprised to see people saying they only work once. Maybe if you pinch the surface between two magnets, or scratch the back, you'll pop the little fluid areas and ruin them? Any way I've kept mine in its paperboard envelope and it seems safe in there. ## Features - SIZE & FILM TYPE - 4x6 Inch single color Green Film. ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B000UV6ZPS | | Best Sellers Rank | #47,041 in Tools & Home Improvement ( See Top 100 in Tools & Home Improvement ) #101 in Industrial Magnets | | Item model number | MVF-002 | | Manufacturer | CMS MAGNETICS | | Product Dimensions | 17.78 x 12.7 x 0.25 cm; 9.07 g | ## Images ![10cm x 15cm Green Magnetic Field Viewing Film, Fun - Image 1](https://m.media-amazon.com/images/I/51NpPdaf9pL.jpg) ![10cm x 15cm Green Magnetic Field Viewing Film, Fun - Image 2](https://m.media-amazon.com/images/I/61XUt4SXFDL.jpg) ![10cm x 15cm Green Magnetic Field Viewing Film, Fun - Image 3](https://m.media-amazon.com/images/I/61fBNZQDQRL.jpg) ![10cm x 15cm Green Magnetic Field Viewing Film, Fun - Image 4](https://m.media-amazon.com/images/I/61s-an8ocvL.jpg) ![10cm x 15cm Green Magnetic Field Viewing Film, Fun - Image 5](https://m.media-amazon.com/images/I/61P4AUi22lL.jpg) ## Questions & Answers **Q: I've previously purchased 5 sheets of 8x12" viewing sheets. I need to buy another 5 of those, or at least 8x8". Will they be available or purchase?** A: yes, they are available for sale but I don't have the list any more. but you can buy 20 pieces of 6x4" and call us so we can cut to the right size since they are equal area. but be sure to call us so we can have the right size for you 972-516-0692 **Q: Is any option to deliver in India?** A: we don't ship Internationally for Amazon. **Q: is it a permanent picture like photo film or does it go away with enough time** A: Its like a liquid crystal sheet. The magnetic image goes away; yet there is a slight memory in the picture. As soon as you bring it up to another magnet, that "ghost image" of the prior viewing goes away.This is very amazing stuff. You can really see a 3D structure of the field as you move close and away from your magnet source.One drawback is gauss responsivity. In other words, I dont thing fields below say 10 guass respond on the film. I will test this later. **Q: What are those little balls in the picture?** A: there is no little balls. they are magnets but not spheres. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Amusant *by A***Y on 21 October 2024* Pratique et ludique pour montrer les champs magnétiques. ### ⭐⭐⭐⭐⭐ Great novelty item *by A***E on 28 June 2019* Not useful for daily things, but great for science experiments and entertainment.
