This allows the user to instantly and clearly see the position of a magnet's poles and the pitching between them. Each sheet is super-thin and flexible meaning it can be wrapped tightly around circular magnets. What's more, each sheet can be used over and over again. Set Contains: 1 x 100mm x 100mm Medium Field Paper Review: Good - Good Review: This is an interesting way to view magnetic fields. It would make an interesting teaching aid. My only slight criticism is that the image is slightly dark (low contrast) so it needs to be viewed under fairly bright light, but otherwise it is quite clear. ## Features - VISUALISE MAGNETIC FIELDS. Visualise magnetic fields with this large, micro-encapsulated film known as field paper. This material allows the user to see the magnetic field produced by any magnet. - THIN, FLEXIBLE, AND REUSABLE. Each sheet is super-thin and flexible meaning it can be wrapped tightly around circular magnets.
