YUMIN Magnetic Viewing Film, 4inchx 4inch Magnetic Field Viewer for Scientific Projects,Reusable and Automatic Recovery

Very suitable for studying and analyzing magnetic fields, and is an interesting for discovering magnets in objects, making it easy to locate the position of the magnets. Magnetic field observation film is made of plastic film containing nickel iron magnetic slurry, which can clearly display the magnetization level and magnetic pole distribution. Frame can fix and protect the film, and the openings on both sides are convenient for extraction. Using magnetic nanoparticles to clearly display the magnetic field mode and intensity, it is very suitable for displaying magnetism and distinguishing between strong and weak magnetic surfaces. Observing all kinds of magnets such as neodymium magnets and . Clearly view magnetic field in objects (magnetic clasp on your door, the speaker on your phone). Visualize the magnetic field lines of different objects and magnets. Our magnetic field viewer is reusable and automatically recovers after use. Simply place it on the of the magnets to observe the magnetic field and determine the direction of magnetization., Weight: 0.04629707502 pounds, Manufacturer: YUMIN
