Neodymium Iron Boron (NdFeB) Rare Earth Magnets. Grade - N40. Dimensional Tolerance - +/-0.005 Inch. Package of 25 Magnets. 1/4 Inch Outside Diameter, 1/8 Inch Inside Diameter, 1/4 Inch Long
Rare earth magnets are the strongest type of permanent magnet currently made. They are amazingly powerful for their size and have innumerable uses. These cylinder magnets are 0.250 inch (6.4mm) diameter, 0.125 inch (3.2mm) inside diameter and 0.250 inch (6.4mm) long. They are magnetized through the length. They are composed of grade 40 neodymium iron boron magnetic material and are plated in nickel-copper-nickel for a shiny corrosion resistant finish. Maximum working temperature is 176 F (80 C). Their individual pull force is approximately 2.6 lbs. Magnets may chip and crack if allowed to snap together.

Size: 1/8 inch diameter x 1/8 inch thick cylinders. Nickel (Ni) Plated (silver-like shine). Grade: N48 - Extremely powerful magnetic material. Pull Force is approximately 1.5 pounds under ideal conditions. Axially magnetized. ONE lot of 50 Magnets. Size: 1/8 inch diameter x 1/8 inch thick cylinders Nickel (Ni) Plated (silver-like shine) Grade: N48 - Extremely powerful magnetic material Pull Force is approximately 1.5 pounds under ideal conditions. These cylinders 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.
