Neodymium magnets are graded according to their magnetic strength. The higher the grade (number) the stronger the magnet. The letter or two letters that may follow the number indicate the Intrinsic Coercivity (Hci) of the material.
The higher the Hci, the higher the temperature the material can be exposed to before the magnet will start to show permanent losses in output. This is what links the letter or letters to a temperature rating.
