Magnaview film

Magnetic Poles of Refrigerator Magnets: visualizing the invisible with Magnaview film- the secrets of refrigerator magnets revealed. A special orientation of the magnetic poles called a Halbach array allows for a strong magnetic field on one side and a very weak one on the other- refrigerator magnets only stick on one side by design! ➡️ Follow the link in my profile for info on where to get Magnaview film samples and many other physics toys. #magnets #magneticfield #physics #physicstoy #magnaview #magnaviewfilm #magneticdomains #amazing #Halbach #Halbacharray #howtheuniverseworks #science #electromagnetism #ferromagnet #magneview #scienceisawesome
