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

Generally speaking, sintered neodymium magnet range from N35 to N55 in grade. Like ferrite magnet,the higher the grade, or N number, the incrementally stronger the magnet will be.

The grades of Sintered 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 rare earth magnet will depend on a number of factors, including the size, shape, and grade.
