Magnetic Field viewer is a micro-encapsulated film which enables the user to view a static magnetic field such as commonly emitted by permanent magnets or dc electromagnets. Simply placing the film directly on the surface of the magnetic material in question can instantly reveal a magnetic field of any shape or pattern.

Magnetic Field viewer is used for quality control, product demonstration, reverse engineering, authentication and educational purposes.
