MIKEDE Magnetic Viewing Film, 4" x 4" Green Magnetic Field Display Film, Magnetic Flux Display, Magnetic Filed Detector, Reusable and Automatic Recovery

OPTIMAL SIZE: 150 mm x 100 mm(6 x 4 inch). Suitable for studying and analyzing magnetic fields, and is an interesting method for discovering magnets in objects, making it easy to locate the position of the magnets
HIGH QUALITY FILM: 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
GREAT EDUCATIONAL TOOL: Observing all kinds of magnets such as neodymium magnets and flexible Magnets. View magnetic field in objects, visualize magnetic field lines of different objects and magnets
FRAME DESIGN: Magnetic viewing film is made of plastic film contain nickel iron magnetic slurry, can display the magnetization level and magnetic pole distribution. Frame can fix and protect the film,the opening on the side is convenient for extraction
REUSABLE AND VISIBLE: Our magnetic field viewer is reusable and automatically recovers after use. Simply place it on the surface of the magnets to observe the magnetic field and determine the direction of magnetization
