Rare-earth magnets are increasingly used in modern industry and DIY projects. Today, we'd like to introduce you to a cost-effective, industrial-grade NdFeB magnet—the N42 Long Industrial Neodymium 75 x 10 x 3mm magnet, ideal for use in generators, motors, and various precision mechanical devices.

Firstly, these magnets utilize N42-grade NdFeB material, which boasts an extremely high magnetic energy product, strong and stable magnetic force, and resists demagnetization. Measuring 75mm x 10mm x 3mm, the slender design not only facilitates installation in confined spaces but also evenly distributes the magnetic field, improving the efficiency of motors or generators. The magnets' surface is nickel-plated for a bright, smooth finish, effectively preventing oxidation and corrosion, significantly extending their service life and maintaining stable performance even in humid or mildly corrosive environments.

Notably, these magnets feature two countersunk screw holes for quick and easy installation. Whether fixed to a metal baseplate or assembled into a rotor structure, screws securely fasten it, preventing movement due to excessive magnetic force and ensuring stable operation. This design is extremely practical for DIY generators, motor modifications, or industrial equipment upgrades, and is particularly suitable for applications requiring high-precision mounting.

Furthermore, this magnet has a wide range of applications. Its powerful magnetic force can be fully utilized in small wind turbines, DC motors, and even laboratory magnetic devices. It is also an ideal choice for electronics enthusiasts and engineers creating magnetic levitation devices, magnetic sensors, or robotic arms.

In summary, the N42 Long Industrial Neodymium 75 x 10 x 3mm magnet is not only powerful, durable, and corrosion-resistant, but also easy to install and suitable for a wide range of applications. Whether you're a professional engineer or a passionate DIY maker, it will bring higher efficiency and a better experience to your projects. Choose this magnet to upgrade the performance of your motors and generators. The magic of magnetism is at your fingertips.
