describe:
This project is easy to use. Simply place the card on the surface of a magnetic material and it will display a patterned magnetic field.
Great for personal or scientific research. It can help us study magnetic fields that we cannot see.
It can be used for quality control, product demonstrations, reverse engineering, certification and educational purposes.
Small and portable, light weight, easy to carry.
A wonderful educational tool to spark our interest in science.
The Magnetic Field Viewer is a micro-encapsulated film that allows the user to see the static magnetic field.
The highly flexible film is suitable for magnetic surfaces with any convexity or cavity.

Much smaller than I thought. Came in a top loader if that gives you any idea.

interesting effect. Note that there is some persistence to the flux image after you pull away from the magnetic source. Can pick up field from a small neo magnet from > 5mm away Coin cell sized neo > 10mm away.
