You are buying one 12 inch x 12 inch sheet of Magnetic Field Viewer Film.
Encased within the green film are millions of magnetic particles suspended in oil. A magnet will attract the particles to the areas where the magnet is the strongest - at its poles. The poles appear dark green. Multiple pole magnets such as those on business card magnets will display interesting patterns, see detail page.
