POWERFUL - Applied Magnets Rare Earth Neodymium Magnets have an estimated pull force of 38 lbs. and are triple layer coated (nickel-copper-nickel) for maximum durability and protection against corrosion. This rectangular rare-earth bar magnet measures 3" x 1/2" x 1/4" and delivers reliable magnetic strength for industrial, laboratory, and commercial applications. Designed for balance between compact form and holding capability, it achieves up to 35 lbs of pull force under ideal conditions, making it a dependable option for mounting, securing, and material handling tasks where precision and consistency matter. Each magnet is constructed from high-performance neodymium material encased in a durable triple-plated nickel-copper-nickel coating. This protective finish provides a smooth surface, corrosion resistance, and long-term stability when exposed to various environmental conditions. The result is a magnet engineered for sustained strength, dimensional accuracy, and repeat performance. Engineering & Construction The magnet’s core composition ensures dense magnetic flux and steady field strength across its rectangular surface. Its design emphasizes linear alignment, which promotes efficient magnetic contact along flat or slightly contoured surfaces. The uniform field pattern minimizes uneven attraction and allows for clean engagement with ferromagnetic materials such as mild steel, carbon steel, and iron alloys. A key advantage of this magnet lies in its coating process. The nickel-copper-nickel system serves three purposes: Corrosion Protection: The outer nickel layer acts as a barrier against moisture and air exposure, delaying oxidation. Structural Reinforcement: The copper interlayer improves adhesion and surface bonding strength. Finish and Handling Safety: The final nickel coat adds a professional appearance and smoother edges, reducing abrasion during repeated use. Every unit is manufactured to meet dimensional tolerances within ±0.004 inches, ensuring compatibility with pre-machined enclosures, fixtures, and mechanical assemblies. This precision allows the magnet to be easily integrated into custom hardware or automation systems where tolerance consistency is critical. Performance Under Ideal Conditions When evaluated under controlled laboratory testing, this magnet demonstrates a maximum pull force of approximately 35 lbs against a thick, flat, clean, unpainted steel surface with full contact and alignment. Actual holding strength will vary depending on the surface finish, air gaps, temperature, and orientation. Users are encouraged to test under their specific conditions for accurate results. The magnet retains stable performance up to around 175°F (80°C). Beyond this temperature, partial demagnetization can occur, reducing efficiency until cooled. It should not be used in environments exceeding these thresholds or in close proximity to heat sources such as soldering stations or ovens. Industrial & Commercial Applications This rare-earth bar magnet serves a broad range of industries: 1. Fabrication & Manufacturing – Used for temporary clamping, metal alignment, jig construction, and assembly holding. Ideal for welders and machinists needing steady magnetic force without physical fasteners. 2. Warehouse & Material Handling – Suitable for magnetizing tool racks, mounting retrieval devices, and organizing ferrous components. It helps streamline production and prevent part loss in high-volume environments. 3. Scientific & Educational Labs – Commonly applied in experiments illustrating electromagnetic principles, field line mapping, or material testing. Durable enough for classroom demonstrations and R&D use. 4. Engineering & Prototyping – Assists with component positioning, sensor calibration, and test fixture development where repeatable, removable connections are necessary. 5. Home & Workshop Utility – Functions as a strong magnetic holder for metal tools, fasteners, and garage accessories. Effective for concealed mounting, DIY storage systems, and small-scale builds. Handling & Safety Guidelines Strong neodymium magnets require careful handling. They can attract metal objects or other magnets wit
