About the Product

Neodymium arc magnets are built for rotor and stator prototypes, magnetic couplings, and curved fixtures. The arc radius nests on hubs or housings so you can assemble partial or full rings to tune pole count and air gap. Magnetization is typically axial through thickness, with radial options for motor development. Tight arc angle, ID/OD, and thickness tolerances support repeatable fits and balance. Estimate attraction with the pull-force calculator, then review grade and temperature limits in the material data and select coatings that suit your test environment.

Customer service

I recently purchased some magnets from overseas. The delivery had been sent wrong and I received someone else's order which was very disappointing. When I contacted SupetMagnetMan with details and some reasonable proof of this mistake, they sent me a new set without question and without any additional cost or hassle to me. I am very pleased with the service and way I was treated.

Hey Andrew,

Thanks for your order and for reaching out once you realized your order had a mistake. We strive to fulfill orders correctly to 100%, but sometimes mistakes can happen. We apologize for the mistake and we are thankful you received the follow up order quickly and correctly.

Thanks again,

Kelley Cameron

Great magnets. I will shop here again.

Magnets were exactly as described. I was press fitting them into a machined part and the dimensions were spot on. Thanks guys. I will shop here for all my magnets in the future.
