Top 10 Best Magnetic Field

Magnetic Field Viewing Film Sheet. Magnetic Field Display. Magnetic Field Demonstrator. Magnet Pattern Detector. Reusable and Automatic Recovery.

Includes 2 magnets .75 inch disc magnet and 1 inch bar magnet and 1 filing-filled tray measuring 3.44 inches in diameter. The small bar magnet has color coded poles red north and blue south.. Features scratch-resistant plastic, rubber-coated magnets, and clean steel flings for clear viewing Filings are sealed inside a mess-free, transparent viewing tray made of special scratch-resistant plastic that stands up to classroom use. Steel filings cleaner than iron filings ensure cloud-free viewing. Magnets are rubber-coated to prevent scratching of the viewing tray.. View a magnets invisible lines of force and manipulate it with our own hands Place a magnet under the dish. Gently shake the dish. Tip the dish to one side, so the extra flings inside fall away from the magnet. Notice how certain areas of the magnet attract more filings. Those areas are the magnets poles. How do the areas of attraction of the disc magnet differ from those of the bar magnet Where are the disc magnets poles Where are the bar magnets poles Breaks in the pattern of the filings inside the dish indicate the separations between the poles of the magnet.. Explore the basics of magnetism attraction, repulsion, polarity, and more. US safety tested for ages 8grades 3..

Used Book in Good Condition.

EASY TO STORE100mm 4inch long, 100mm4inch wide. Very 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 FILMUsing 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 TOOLObserving all kinds of magnets such as neodymium magnets and flexible Magnets. 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.. UNIQUE FRAME DESIGNMagnetic 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.. REUSABLE AUTOMATIC RECOVERYOur 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..

Green Micro-Encapsulated Film used to Show Magnetic Field, or Test Cracks on Steel Surfaces. Very Interesting to Actually See the Magnetic Field It is Flexible so can be Wrapped around the Tested Magnets. Applicable to All kinds of Permanent Magnets, Such as Neodymium, Ceramic, SmCo, AlNiCo and Flexible Magnets. To Expose Magnetic Field, Place Directly on Top of the Magnets. The Magnetic Field Pattern Stays on the Film so You can Further Analyse it till Next Use. Wonderful Educational Tool for Magnetism Study and Analysis.
