Neodymium Rings

Neodymium rings are rare earth magnets formed by the alignment of neodymium, iron and boron, which have a cylindrical shape with a hole in the centre of the magnet that produces a magnetic field.

The magnetisation of neodymium rings is axial and the north and south poles are normally located on the circular faces of the magnet.


Neodymium magnet rings are the most commonly used type of magnet due to their holding power.

Neodymium magnet rings are characterised by their high performance and high power. This type of neodymium magnets can be used in various sectors such as automotive and medicine among others; more specifically in microphones, door locks, jewellery, motors, wind turbines, magnetic separators, loudspeakers ....

Standard sizes:

The standard sizes we manufacture can be seen below. Also, if other sizes are required, we can manufacture them according to the customer's needs.

Size range A (mm) C (mm) D (mm)
5-240 1-100 1-210


Neodymium rings have a low resistance to corrosion, so they need a nickel coating to protect the magnet from external factors.

Maximum working temperature:

The ring-shaped neodymium magnets have a resistance of 80ºC so that we can work with them and manipulate them according to our needs and the application for which we are going to use them.
