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 nouth 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 degrees Celsius.
