Neodymium arc magnets are engineered for use in motors, generators, magnetic couplings, and curved magnetic assemblies, where controlled torque and rotational force are essential. At SuperMagnetMan, we carry a robust selection of arc magnet assemblies that are radially magnetized, nickel plated, and available in various sizes to support both prototyping and production needs.

These arc segments are ideal for: brushless DC motors, generators, magnetic (torque) couplings, rotor assemblies, and precision motion systems.

Our standard inventory includes a small number of high-temperature arc options, with detailed specifications on grade, size, and magnetization direction available on each product page. If you require a unique size, coating, or configuration, we also offer custom arc magnet solutions designed to meet specific engineering requirements.
