Green Stuff World Neodymium Magnets 3x1mm - 50 units (N52)

SKU: GSW-9259 | Brand: Green Stuff World | Product: Green Stuff World Neodymium Magnets 3x1mm - 50 units (N52) Specifications: 3mm diameter, 1mm thickness, 50-unit quantity, N52 magnetization grade, 126gr pull force (magnet-to-magnet), NdFeB material with Ni-Cu-Ni nickel plating. Neodymium magnets represent the strongest permanent magnet category available commercially, serving as replacements for alternative magnet types in modern applications requiring high magnetic strength. The alphanumeric designation indicates material quality: N35 and N52 grades measure magnetic energy density per volume and maximum operational temperature. Higher numerical values denote increased strength and heat tolerance. N-grade magnets function effectively up to 80°C (176°F), with N52 representing the highest-grade neodymium magnet currently manufactured. Magnetic strength differences between magnets of varying sizes and grades correlate primarily to volumetric differences rather than magnetization classification variations, making larger magnets typically stronger regardless of slightly lower grade designations.
