If you buy this, CHECK OUT A REFRIGERATOR MAGNET! I always thought those cheap magnets were unnoteworthy. It blew my mind to see (and then learn after some googling) that they're a clever arrangement of magnetic field domains known as a Halbach array, which doubles the field on one side (the back) and essentially cancels it on the other (the front). See the striped pattern in my first picture, and check out the Wikipedia articles on Halbach arrays and on refrigerator magnets for more info. For a cool effect, try stacking two fridge magnets and look at the interference patterns as you rotate one while holding the other steady.What caught my attention about this particular viewing film was its multi-color nature based on field strength (many others are monochromatic) and the fact that it "resets" as the fields are taken away, allowing you to see what magnetic fields are currently present and not some mess of the past history. The film appears to change almost immediately at room temperature (not sluggish) as you move a magnet. I don't know how fast it actually is, but I suspect it wouldn't keep up with very rapid changes.This viewing film came with a rigid protective plastic case and a little card showing a rough scale for color versus field strength. I'd take the numbers with a grain of salt, but the color gradient does add some nice qualitative information about the shape and strength of the fields. Colors indicate fields normal (perpendicular) to the plane of the film, and the neutral brownish-yellow color indicates either no appreciable field strength, or fields that are tangential (parallel) to the plane of the film. Although you can't differentiate between North and South, you can easily see where fields are concentrated and where the magnetic field direction changes.Also pictured on the included card is an indication of how the film works. Just guessing, but it looks to me like it might be a thin-film interference effect, where the interference region thickness (which sets the color) depends on how strongly pulled down the internal particles are (which depends on field strength).This would make a great gift for STEM-interested folks (kids and adults alike). ### ⭐⭐⭐⭐⭐ View of magnets is nice. Showing details you would miss with iron filings. *by P***. on November 26, 2024* Crisp lines at the edge of the magnet and change of color extending beyond showing the field strength.I have an old hard drive magnet that shows two reddish fields about an inch away from the magnet. You put the film next to the magnet it shows blue/purple edges. green toward the middle and a one inch complex yellow field around the whole thing. A broken stack of magnets or the back of an iPhone is very interesting to look at. ### ⭐⭐⭐⭐ Relative magnitude color chart could be improved *by F***Y on May 26, 2025* The media could not be loaded. It is great for relative magnetic field strength.
