When you see designations such as N35, N42, or N52, these numbers represent the grade of a neodymium magnet. The grade indicates the maximum energy product (BH)max, measured in MGOe, which reflects the strength of the magnet.
- Higher numbers (e.g., N52) indicate stronger magnets at room temperature.
- Lower numbers (e.g., N35) are less powerful but more cost-effective.
Understanding these ratings is the first step in choosing the right magnet for your application.
