Product Description
N42 Neodymium Ring Magnet 3" x 1/2" - Strong NdFeB Rare Earth Ring Magnet with High Pull Strength for Industrial, Motors & DIY
In 2026, if you're looking for a N42 neodymium ring magnet that combines impressive size with powerful holding, this strong NdFeB magnet (3" outer diameter x 1/2" thick) is an outstanding option. These rare earth ring magnets offer high pull strength in a versatile ring shape, making them perfect for users seeking neodymium ring magnets for sale or powerful N42 ring magnets for demanding applications.
Crafted from premium N42 neodymium (NdFeB) alloy under strict ISO 9001 quality standards, this 3 x 1/2 neodymium ring delivers superior remanence (12,800–13,200 Gauss or 1.28–1.32 Tesla) and is axially magnetized for optimal performance on flat surfaces. The durable NiCuNi (nickel-copper-nickel) triple-layer coating provides excellent corrosion resistance, ensuring longevity in industrial and workshop environments.
Key Features & Benefits:
- High Holding Power: This strong N42 ring magnet provides robust pull strength – ideal for heavy-duty holding in industrial settings, motors, generators, and magnetic separation systems.
- Precision Ring Design: Tight tolerance of +/-0.002" (including coating) guarantees consistent size and reliable results for threaded or centering applications.
- Versatile Applications: Perfect for industrial use (tool holders, machinery, wind turbine components), DIY projects (custom fixtures, model building, crafts), and holding systems (securing tools, equipment, or assemblies). This powerful rare earth ring magnet is also popular for sensors, generators, and automotive repairs.
- Durable & Reliable: Nickel coating resists chipping and oxidation in normal indoor conditions; backed by a 10-year magnetic strength warranty under standard use.
Why Choose This N42 Neodymium Ring Magnet? In the world of neodymium ring magnets, the N42 grade offers an excellent balance of strength, affordability, and reliability, making it stronger than N35 equivalents while being more cost-effective than premium N52 options. If you're seeking a strong NdFeB magnet for rigorous tasks, this 3 x 1/2 neodymium ring delivers unbeatable force in a ring shape. Compared to ferrite alternatives, it provides compact power without sacrificing durability – perfect for upgrading from weaker magnets.
Environmental Limits This N42 neodymium ring magnet operates optimally up to 80°C (176°F), with demagnetization risks above the Curie point (~310°C). For high-heat applications, consider our temperature-rated variants. The coating suits dry indoor environments; avoid prolonged moisture without extra safeguards.
Safety & Usage Notes: Strong rare earth ring magnets can chip or shatter if mishandled – always handle carefully. Keep away from pacemakers, electronics, and children. Not recommended for outdoor or high-humidity applications without protection (warranty voided by extreme conditions).
