That looks like the type with nickel flakes to me (https://en.wikipedia.org/wiki/Magnetic_field_viewing_film https://en.wikipedia.org/wiki/Magnetic_field_viewing_film), as it's not showing different colours

- blincoln 3y ago> That looks like the type with nickel flakes to me I agree. It's a night and day difference versus the magnetochromic viewing film. The monochrome film doesn't reset itself after the field is removed,[1] and the contrast is not as good. I bought both types on Amazon a few years ago. The specific magnetochromic film I bought at the time disappeared from Amazon (along with its vendor) shortly thereafter, but it seems like at least one seller has the same kind of product again.[2] [1] I suppose this might be useful for some applications, but I dislike the "ghosting" effect.
