What does the N rating on neodymium magnets mean?

The magnet grade, or N rating refers, to the Maximum Energy Product of the material that the magnet is made from and it refers to the maximum strength that the material can be magnetized to permanently hold.

Generally speaking, neodymium magnets range from N35 to N55 in grade. The higher the grade number, the incrementally stronger the magnet will be.

 Neodymium Magnet Grade Chart

The grades of neodymium magnets that we normally carry are N42, N48 and N52, a rating that is generally measured in Tesla metrics or units of Gauss Oersted (MGOe).

A magnet of grade N42 has a Maximum Energy Product of Gauss 42 MGOe, while an N52, at 52 MGOe, would be incrementally stronger.  

It is important to note that the N rating is a measure of the maximum energy product of the magnet, and it does not necessarily reflect the actual strength of the magnet in a particular application. The strength of a magnet will depend on a number of factors, including the specific properties of the magnet and the configuration of the magnetic field.
