Magna View Film is mylar film that reads magnetic fields. It is very useful when you suspect that there may be leakage from a transformer or circuit device. The Magna View Film can be used to check and determine whether there actually is any leakage present.
The Magna View Film has encapsulated chambers containing dry ferrous magnetic material. The film is waterproof, tear resistant, flexible and best of all, reusable. You will receive two 4"x4" sheets that are 0.006" thick. (Magnet not included)
