Green Magnetic Viewing Film 4x6 | Cool Magnets Science Kit | Magnetic Field Detector & Visual Aid for Physics Education | Ideal for Research & Magnetism Demonstrations

This magnetic viewing film is awesome for visualizing magnetic fields clear, responsive, and perfect for science demos or teaching. Great size and fun for kids and adults alike. A cool addition to any STEM kit.

My husband loved it

Worked well to show the magnetic fields for science project.

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.

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.

Just don't expect any dramatic lines of force extending away from the magnet. What you'll get is gradations of darkness in the immediate vicinity of the magnet.

I work in IT and I used to use a larger version of this same type of product but need something smaller. This is incredibly helpful in locating speakers or magnets that assist in putting devices to sleep or lock displays. Sometimes when you are blindly tearing down devices you may have to separate screen from enclosures and it can be helpful to know what is around the area you are prying at.

Can barely see anything, even with fairly strong magnets. Maybe this is the limit of this tech but probably better to just get a little clear plastic box filled with iron filings or something.
