Custom Neodymium Arc Magnets – Wholesale Large & Small Curved Magnets
Neodymium arc magnets are strong curved rare earth magnets. With unique shape – segment, a set of diametrically arc magnets can be used to form a ring. Arc magnets make up for the shortcomings of ring magnets.
They are the most popular shape of permanent magnets and typically used in permanent magnet motors, generators and torque couplings, pumps, magnetic bearing, halbach.
What’s more,
can you imagine it? It can also be used for Magnetic Nail Polish!
What Is the Reason for Using Curved Magnets?

- Too big neodymium ring is hard to make.
- Special magnetization direction can’t be made on magnet neodymium ring, such as radiation magnetizing
- Actual situation needs. For example, rotor and stator are cylinder, having curved magnets will allow magnets get closer to the stator. So it can decrease air gap and increase the flux between them.
Specification of NdFeB Arc Magnets:
- Highest Quality Material: super strong neodymium magnets
- Multiple Grades: N35UH and N35SH, N40SH, N42SH, N38UH N52M, etc. Here choose more from our Neodymium Arc Magnets Grade.
- Wide Rang Of Working Temperature: motor and generator will generate a lot of heat and energy in high speed running. So, the built-in neodymium arc magnets have to withstand high temperature in operating, our max. working temperature range from default (up to 80 °C or 176 °F) to AH (230 °C or 446 °F).
- Durable Plating: to give superior corrosion resistance and provide a smooth and clean finish, arc magnet neodymium needs to be coated. The most common coating on curved magnets is epoxy. Zn and NI+CU+NI triple layer coating are also available. Here choose more from our Neodymium Arc Magnets Coating.
- Shape Variant: tile, bread, wedge shaped and arched magnets
- Size Range: 2≤L≤158mm, 3≤W≤90mm, 1.5≤T≤50mm, more details, please contact us directly.
- Tight Tolerance – ±0.05mm (±0.002”)
- Magnetiaztion Direction: each magnet’s north and south pole are on opposite flat faces or choose from our Magnetization Direction of Neodymium Arc Magnets.
- Limitless Uses: the strongest permanent magnet in the world and can provide more powerful, therefore, neodymium segment magnets can be used for a wide variety of projects around the house and industry, including motor, water treatment, wind turbine, nail beauty, camera lens.
