Good product
Comes in a cardboard frame. Works very well to see magnetic strength and pattern.

You need a strong field to see the effect, but it's pretty amazing.
I have been using the green field viewer sheets for years, and they are great, but I was looking for something that made a clearer image. So I got some of these. And they are amazing! I thought they'd be good, given the reviews, but I assumed that the photos were faked. They aren't—you really do get different colors and a very striking pattern when you have an interesting magnetic field to make visible. The only downside is this: This film only works on really strong fields. Refrigerator magnets.... Nope. You need strong rare earth magnets to see a good effect. But if you have strong magnets and you need to make a striking visualization of their field.... This is a great tool for the job!

Works just like the description. 🤩

It works but is not bright at all
It works but I don't know how strong the magnets have to be to get it to show up as well as the images make it look. The magnet in my Pixel 11 is barely visible.

Accurate, Versatile Tool for Diagnosing and Exploring Magnetic Fields
This magnetic field viewing film performed exactly as I needed—clearly showing the magnetic field pattern of a camshaft sensor’s target magnet so I could confirm it was functioning properly without wasting money on unnecessary parts. The detail it reveals made diagnosis quick and confident. Beyond that single repair, it’s become a fascinating tool for exploring magnets in everyday items and seeing how their fields are arranged. The film is reusable, easy to handle, and has already provided more value than I expected—both for practical troubleshooting and satisfying my curiosity.

This material is sensitive to magnetic fields.
Good material reveals magnetic fields, sensitive, and a good frame. It will help me with coil winding project. Good value.

Awesome toy and useful for subjective comparisons of magnets
Have had a lot of fun with this product. It is geared towards stronger magnets, as it doesn't reveal data on magnetic stripes. Good for subjective comparison of magnetic strengths. Pictured: an N52 round beside a weaker (maybe N35?) rectangle.

Only Good For Very Strong Fields
Does it work? Yes. But it’s not so revealing unless the magnetic field is VERY strong.

Pretty alright
It’s ok.
