NISHZHU Magnetic Viewing Film, 6inchx 4inch Magnetic Field Viewer for Scientific Projects,Reusable and Recovery

• Magnetic field observation film is made of plastic film containing 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 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 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.
• 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.
• Our magnetic field viewer is reusable and automatically recovers after use. place it on the of the magnets to observe the magnetic field and determine the direction of magnetization.
