Arc Magnets-N38 is one special shape of Rare earth magnets and permanent magnets. It is always manufactured via Wire Cutting and grinding etc. Regular Arc magnets or Segment magnets have the following important factors such as, Outer Diameter Or Outer Radius, Inner Diameter or Inner Radius, Degree of Angle, Thickness, Length, Round Edge etc
