37.5 O.R x 33.5 I.R x 25mm x 4mm thick N42 Neodymium Arc Magnet

• 25mm high x 4mm thick, with an outside radius of 37.5mm and an inner radius of 33.5mm.
• The magnet's south pole is on the inside radius and the north pole is on the outside radius.
• Four of these south arc magnets with four of the north version are required to create a 360^o 8-pole ring.
• Coated with three layers of nickel, copper and nickel to reduce corrosion and provide a smooth and clean finish.

Commonly used in motors for both rotors and stators, these high-performance Neodymium (N42) arc magnets have an anisotropic alignment and a maximum operating temperature of 80^oC.
