CMS MAGNETICS - 6x6 Green Magnetic Flux Viewing Film for Revealing Hidden Magnetic Field Patterns in Permanent Magnets for Science Projects, Research and STEM Education in Magnetism

Now that i got your attention, this green magnetic field picker upper is a fun toy for the kids when they are playing with magnets. Good for seeing the patterns of magnetic fields, and easy to wipe the pattern off the paper with another magnet. Not sure about finding hidden alien devices, but you never know.

This film works exactly as advertised, showing magnetic fields while still being mostly translucent. An absolutely perfect teaching tool for elementary physics classes everywhere. Highly recommend!

I saw this film on a YouTube video. It showed where all the magnets are in the iPad. I got it because I’m curious and had to see it in person. For the low price it’s well worth it. I’m not sure what else it could be used for but I’m sure there’s something. I did send this to the grandkids and they had fun with it too. For the cost of a kids meal it’s fun to get and try out.

I have a 250lb pull-weight magnet and it barely darkens this film at all. I regret buying it.

not helpful, the paper always shows the image of the last magnet it touched, does not show magnetic field.

Works as described

Although this was used for strong magnets, the contrast was poor at best. IMHO Not worth the money.

My husband loved it
