3.The magnetic viewing film can then be used to "see" the pattern of magnetization. When a magnet is placed under the viewing film, the tiny metal flakes respond to the magnetic field, forming shapes similar to the pattern of magnetization 1.Magnetic Film for Visualizing Magnetic Fields 4.Frame design protects the magnetic viewing paper 2.Magnetic viewing film is made of millions of tiny magnetic flakes 5.This is a good tool for science and education, to show students the application of magnets in their lives. and this magnetic field detector is excellent for discovering and observing new things, Weight: 0.05842249943 Pounds, Manufacturer: Jaywool
