Field paper is made from material known as micro-encapsulated film which changes color when it reacts to an external magnetic field. 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.
