Magnetic Pole Viewer

A Magnetic Pole Viewer is used, as the name suggests, to view the magnetic poles of a magnet, and to display where the magnets are located in an object. It is a green, translucent, thin flexible sheet, coated with micro-capsules containing nickel flakes suspended in oil. When the film is placed on a magnet's pole, the area of the pole appears dark.
