Magnetic field viewing film 50 x 50 mm
 
The 50 x 50 mm magnetic field viewing film is designed for quick visual inspection of pole patterns on the surface of permanent magnets.
 
When placed near a magnet, it reveals the distribution of polarity and the general magnetic-field pattern, making it practical for demonstrations, technical inspection and comparative testing.
 
Suitable for education, laboratories and workshops, especially when a magnetic field needs to be visualised quickly and clearly.
