For neodymium block magnets, although most are magnetized in thickness, some customers have special requirements and need magnetization in length or width. The following is an introduction to these three magnetization directions.
The first type is magnetization along the length. The magnetic field of the magnet runs along the long side of the rectangular block magnet, i.e., from one end of the rectangular block to the other. This type of magnetization is suitable for applications that have specific requirements for the polarity of both ends of the magnet, such as sensors.

Three magnetization directions of neodymium block magnets

The second type is magnetized along the width direction, with the magnetic field direction along the width of the rectangular block magnet, i.e., from one side of the wide surface to the other, as shown in the first type in the image above.
The third type is magnetization along the thickness direction, which is the most common. The magnetic field direction is perpendicular to the thickness of the rectangular block, i.e., the magnetic field formed between the two end planes (thickness direction) of the magnet. The magnetization diagram is shown in the last image above.
When selecting the magnetization method, it is necessary to decide based on the specific requirements of the application. If you have any questions, please feel free to send us an inquiry.
