Neodymium Blocks

Neodymium blocks are a class of permanent magnets which are made of an alloy of neodymium, iron and boron. These magnets have a high coercivity and a high remanence.

The magnetization of the neodymium block, that is to say, the north pole and the south pole of the magnet, is found on the two largest surfaces of the neodymium block.


Neodymium blocks have high adhesive holding power due to neodymium which is the latest generation of rare earths with high magnetization. Neodymium magnetic blocks are characterized by being a square magnet.

Block-shaped neodymium magnets are used due to their high magnetic properties in different industrial sectors such as automotive, electronics, and advertising; more specifically in engines, hospital machines, and car sensors, among others.

The neodymium blocks are of very good quality, they are mostly Nd35 and Nd38. From the point of view of magnetization, they have an axial.

Square-shaped neodymium blocks are often used for motors, speakers, and car sensors.


Standard sizes:

The standard sizes with which we work with neodymium blocks can be seen in the table. When choosing the size of the neodymium magnet, we have to take into account that the neodymium magnet is the most powerful of the permanent magnets, that is, it has a lot of magnetic force concerning the size of the neodymium block. You can also find all the sizes of our neodymium blocks below.

Size range A (mm) B (mm) C (mm)
8-100 2.8-100 1-25


The square-shaped neodymium blocks are delivered with a nickel-plated coating as a consequence of their low resistance to corrosion and external factors. The greater the area of the pole face, the greater the attraction of the magnet. Unlike the various formats of magnets; Neodymium blocks having a flat shape allow for greater use and handling when dealing with them.

Maximum working temperature:

The working temperature of standard neodymium blocks is 80°C. For a higher working temperature, please contact our sales department.
