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

PERMANENT MAGNETS

A permanent magnet is made from a material that is magnetised and creates its own persistent magnetic field. An everyday example is a refrigerator magnet used to hold notes on a refrigerator door. Materials that can be magnetised, which are also the ones that are strongly attracted to a magnet, are called ferromagnetic (or ferrimagnetic). These include iron, nickel, cobalt, some alloys of rare earth metals, and some naturally occurring minerals such as lodestone. Although ferromagnetic (and ferrimagnetic) materials are the only ones attracted to a magnet strongly enough to be commonly considered magnetic, all other substances respond weakly to a magnetic field, by one of several other types of magnetism.
