30 Neodymium Magnets 5/16 x 1/8 inch Disc N48
ONE lot of 30 Magnets. Size: 5/16 inch diameter x 1/8 inch thick discs. Nickel (Ni) Plated (silver-like shine) Grade: N48 - Extremely powerful magnetic material Pull Force is approximately 3.8 pounds under ideal conditions. These discs are axially magnetized, so the strong North/South poles are in the center of the flat sides. That makes them easier to stack into a cylinder than to connect side by side. The metal coating is durable, but ALL Neodymium magnets can chip or shatter. If used gently, these magnets can serve you for a lifetime.
