Magnetic Flux Viewing Film 6"x4", Magnetic Field Display, Magnet Pattern Detector, Scientific Project Teaching, Reusable and Automatic Recovery - Brownish Yellow

I love playing with magnets and creating fun games and devices with them. I've used green magnetic film in the past, but never found it that useful. This film, on the other hand, provides so much more information on magnetic fields and gradients in a colorful display that's pleasing to the eye. I have a feeling this is going to help reduce the trial and error loop I go through when developing new ideas. Highly recommended for hobbyists and educators. I'm sure professionals could benefit also!

Fun for little kids and helps young students learn about magnetic fields. Paper frame was not well sealed around the edges, so you might have to use some tape or glue (with caution).

My students got a few minutes of fun with it and that was all for about $50 price. Not with it!!!

Needed a way to visualize the magnetic fields in a part holding device used in a robotic automation cell. This viewing film was exactly what we needed.
