Product Description
Custom Neodymium Arc Magnets Segment Magnet for Motors · High grade Neodymium magnets manufacturer NdFeB arc magnet
Arc magnets are a unique shape that is designed especially for motors, generators, and alternators and are commonly used for both rotors and stators. They are also used in magnetic flywheel assemblies. In motor design, a ring of magnets with alternating polarities on the inner radius rotates in close proximity to a number of copper coils. As the copper passes through the magnetic fields an electric current is induced within the copper. Four or more magnets with an equal number of north and south polarity on the inner radius can be used to create a multi-pole ring. All arc magnets are available with either pole on the inner radius.

FAQ
1. Which is the strongest type of magnet?
Neodymium (more precisely Neodymium-Iron-Boron) magnets are the strongest permanent magnets in the world.
2. What are neodymium magnets?  Are they the same as "rare earth"?
Neodymium magnets are a member of the rare earth magnet family. They are called "rare earth" because neodymium is a member of the "rare earth" elements on the periodic table. Neodymium magnets are the strongest of rare earth magnets and are the strongest permanent magnets in the world.
3. What's the Grade of a magnet?
Atech Neodymium Permanent Magnet is graded according to its maximum energy product, which relates to the magnetic flux output per unit volume. Higher values indicate stronger magnets and range from N35 up to N52.  and M, H, SH, UH, EH, AH series, can be customized into a wide range of shapes and sizes with precise tolerances. Multiple choices of coatings and magnetization orientations can meet specific customer requirements. Letters following the grade indicate maximum operating temperatures (often the Curie temperature), which range from M (up to 100 °C) to EH (200 °C) to AH (230 °C)
4. What materials do magnets attract?
Ferromagnetic materials are strongly attracted by a magnetic force.  The elements iron (Fe), nickel (Ni), and cobalt (Co) are the most commonly available elements. Steel is ferromagnetic because it is an alloy of iron and other metals.
5. What materials can I use to block/shield magnetic fields?
Magnetic fields cannot be blocked, only redirected. The only materials that will redirect magnetic fields are materials that are ferromagnetic (attracted to magnets), such as iron, steel (which contains iron), cobalt, and nickel. The degree of redirection is proportional to the permeability of the material. The most efficient shielding material is the 80 Nickel family, followed by the 50 Nickel family.
6. How is the strength of a magnet measured?
Gauss meters are used to measure the magnetic field density at the surface of the magnet. This is referred to as the surface field and is measured in Gauss (or Tesla).  Pull Force Testers are used to test the holding force of a magnet that is in contact with a flat steel plate. Pull forces are measured in pounds (or kilograms).
7. Can I cut, drill, or machine neodymium magnets?
The Neodymium Iron Boron material is very hard and brittle, so machining is difficult at best.
