Windspeed Magnetic Field Viewing Film, 4x4 Inch Reusable Magnet Pattern Detector Magnetic Flux Display Magnet Detecting Paper to Show Magnet Detecting Paper

Features

• Show Magnetic Field: Place the magnet on the back of the magnetic field viewing film, which can clearly show the magnetic field line diagram of the magnet. Different colors represent different magnetic grades.
• Material: The magnet pattern detector is made of brown magnetic nanoparticle film material with a frame added to protect and secure magnetic nanoparticle film.
• Automotive Recoverable: After the magnet is away from the magnetic flux display, the magnet detecting paper will automatically return to its original color. After the magnet is placed on the back of the product, different colors will be generated again to show the magnetic level.
• Widely Application: The magnetic field viewer card can be used to observe various magnets in daily life and judge the magnetic force level of magnets, such as magnetic buckles.
• Good Study Tool: The magnetic field viewing film can visualize the magnetic level of the object and see the magnetic level of the magnet more quickly. It is an excellent learning tool for studying and analyzing magnets.
