This material is very helpful. I have been trying ...

This material is very helpful. I have been trying to arrange magnets in a particular pattern, but was only guessing as to how they affect each other. With this material, I can see how the magnetic fields are shaped as they attract or repel each other. Don't expect to see the lines that iron filings may produce, but there is a clear line between north and south of each magnet and at the intersections of the various fields. I should have bought this in the beginning.

Still haven’t used it for anything but it’s cool.

Me: Looks honey, I can see through this magnet... Her: You’re an idiot. Me: I’ll use this for something. Still haven’t used it for anything but it’s cool.

Good enough for the girls I go out with!

Pretty skookum, easy to use what for telling if your magnets are gonna chooch

Fun way to view magnetic fields

This is a lot of fun to play with. I have several different kinds of magnets, each giving a different visual effect. Cube magnets stuck together in a 4x4 array give very interesting visual effects. I can see how the magnetic fields bend around and in between each magnet in the array of magnets. I have some ceramic magnets that have multiple poles on each surface. With this film I could actually see exactly where the poles were in the magnet surfaces. They are all in perfectly straight lines across the faces. I could also see that my weak multiple pole magnets actually had their poles moved into different positions. There were no longer straight lines on them dividing the poles. The lines were all wacky. They were damaged from being too close to stronger neodymium magnets. I could even see magnetic field marks on them left behind from the neodymium magnets. Very fascinating. This product is exceptionally kid friendly. My kids loved playing around with it. This is similar to using iron shavings to view magnetic fields, but it's not at all messy, and a lot more beautiful. My kids were actually drawing pictures on it with magnets. What fun!

Great Inspection Tool for Magnetic Seals on Wheel Bearings

We bought 2 of these as Wheel Bearing Check Tools to make sure any of the North/South Magnetic poles on an embedded Wheel Bearing that's also the Speed Sensor ring for an ABS system are okay from packaging and shipping damage- Once you place the Film on top of one of these bearings, the Magnetic sections in the seal just jump right out visibly, and you can spot if any of the tiny magnetic poles are damaged or are all okay before you start pressing the bearing into a hub assembly. Wish we'd known about these very inexpensive tools years earlier, since ABS type speed reading bearing systems only need a single magnet pole damaged to store a Trouble Light or warning light on your dash. Without the Film to show the magnetic poles, the seals look fine to the naked eye and you'd never know a bearing might have slight damage to its seal before you installed it.

Fun to play with, great to show kids too!

I started by taking just a few different fridge magnets to show my nieces/nephews and they loved to see the rows of magnetic direction. But, when you take it to the sides of a newer iPad, you can see all the connection points where a magnetic case will fit. It's such a simple way to visualize magnetic fields.

It Works Well

I love it! It works as described and as shown in the picture. I'm not sure if the negative reviewers got faulty sheets or if they just don't understand what it is supposed to look like. It definitely works. It's very cool. Definitely play with a wide variety of different magnets. It is usually most interesting with a series of magnets joined together as shown in the pictures. Have fun!

Ave hack.

Not going to lie, got the idea off of AvE. Works just like in his videos. Fun to use in the garage. Just do not bend it.

Worked perfect for determining poles

This film works as advertised. I came packaged in a nice stiff cardboard folder which prevents damage and can be reused for storage. This film was used to determine where the poles were on a magnet used in an absolute angle hall effect position sensor. One could clearly determine where the centerline of the magnet was for proper mounting.

Works as expected.

The product works as expected. I used them to visualize the magnetic field produced by Zen Magnets (5mm spherical magnets used for creative building projects and stress relief). These magnets are strong enough to show an obvious pattern on the viewing film, although you must take care to be gentle with the film, as pinching or folding can cause the film to become damaged and release a small amount of green residue. Do not allow two magnets to be mutually attracted across the film, as if they are allowed to come together, the pinching force will likely damage the viewing film. Damaged areas of the film will permanently remain a fixed color, and therefore not respond to fields in this region.
