Product information "Flux-Detektor Foil, 7,5 x 7,5 cm"
The Flux-Detector makes magnetic fields visible.
It turns dark in color when the magnetic field is perpendicular to the foil and turns lighter when the magnetic field runs parallel to the foil.
This characteristic opens a lot of possibilities for geocachers, to hide information completely invisible with the help of some magnets and let them appear with the help of the foil, hidden nearby.
- Foil filled with nickel particles in a gelatinous suspension
- Measurements: approx. 75 x 75 mm
- Weight: approx. 2 Gram
- Possible to laminate the foil and it will still work fine
