You’ll get the same high-quality construction and power of our Horseshoe Alnico I Magnet series with this set of two Alnico I Disk Magnets. Each magnet is carefully magnetized along a diameter. Flat surfaces are smoothly ground so they fit closely to each other-or to other objects. When placed together with like poles adjacent, the upper disk will reverse itself instantly. With an average field strength of 520 gauss, each disk is 4.0cm in diameter and 7mm thick.
