Cylinder Magnets or Rod magnets is one popular shape of Rare earth magnets and perment magnets.It is always manufactured via Cutting, Slicing, Centerless grinding, etc.Cylinder magnets have the following important factors such as, Diameter and Height etc.
Cylinder Magnet Feature:
Neodymium-iron-boron magnet is one kind of the permanent magnets.
Magnet N-( N35, N38, N40, N42, N45, N48, N50, N52),
Magnet M-(35M, 38M, 40M, 42M, 45M, 48M, N50M),
Magnet H-(35H, 38H, 40H, 42H, 45H, N48H),
