The N35-6x4 is a small but powerful sintered neodymium-iron-boron (NdFeB) disc magnet with a grade N35 energy rating. It measures 6 mm in diameter and 4 mm in thickness with a tolerance of ±0.1 mm, making it suitable for compact assemblies where space is limited but magnetic strength is critical. The magnet is axially magnetized through its thickness, so the north and south poles are located on the two flat circular faces.
Its nickel coating provides a degree of corrosion resistance, and the standard N35 grade offers a practical balance between magnetic performance and cost. This strong rare earth magnet is widely used in craft projects, sensor triggering (such as Hall-effect and reed switches), small motor and generator assemblies, magnetic holders, and educational demonstrations. Typical pull force for this size and grade is in the range of approximately 0.9 to 1.3 kg, depending on the mating steel surface and contact conditions. Users should note that sintered NdFeB is brittle and can chip if allowed to snap together forcefully, and the maximum recommended operating temperature for standard N35 is 80°C. This NdFeB magnet is a practical choice for compact magnetic assemblies, DIY projects, and precision sensor applications.
