Magnetic Field Viewing Film 4"x4", Magnetic Flux Display, Magnet Pattern Detector, Scientific Project Teaching, Reusable and Automatic Recovery,Magnetic Field Viewer - 1Pack
Magnetic Field Display: Brown magnetic nanoparticles film is used to show magnetic field, clearly showing the patterns of magnetic field lines of magnets. Different colors represent different magnetic field intensity Unique Design: The magnetic field paper is made of plastic film that contains a ferromagnetic slurry of fine nickel, and the frame outside can fix and protect the film
Widely Used in Daily: Ideal for observing all kinds of magnets such as SmCo, AlNiCo, Neodymium and Flexible Magnets. Clearly view magnetic field in objects. Magnetic clasp on your door, the speaker on your phone, or concealed buckle of the handbag
Wonderful Tool for Study: Just put magnetic field viewing film on little things, discover and analyze magnetic fields, and open your mind to calculate the value of the magnetic field, even if change the magnetic pattern
Unique Design: The magnetic field paper is made of plastic film that contains a ferromagnetic slurry of fine nickel, and the frame outside can fix and protect the film
Reusable and Automatic Recovery: Our magnetic field viewer is reusable and automatic recovery after use, just place it on object surface to observe magnetic field
