We have mounted a very powerful 3/8" diameter x 3/8" diameter cylinder N52 grade neodymium-iron-boron rare-earth magnet in brass for industrial and hobby use. It comes with a split ring for easy carrying, and comes with a protective vinyl cap. The magnet insert is rated at 10 lbs (as with all magnets, this rating depends on the magnet mating to a smooth, flat, unpainted steel surface). These 10 lb magnets have an excellent feel and are very sensitive. The perfect size and strength for identifying fake silver & gold jewelry! Please note: Due to their strength they all have the potential to damage credit cards or other items with a magnetic strip if they are kept too close, but cell phones and electronics are fine. The brass casing protects the magnet from chipping and breaking, and makes removing iron and steel shavings much easier. Proudly made in the USA! Dimensions are: 1/2" (12.5mm) diameter x 3/4" (19mm) tall head, 1-7/8" (48mm) overall length, 3/8" (9.5mm) diameter handle, 1/2" (12.5mm) diameter stainless steel split ring.
