Magnet Grade

Neodymium Magnets Grade:

Neodymium magnets come in different grades such as N35, N38, N40, N45, N48, N50,  N54, N42, N52 or N42SH.

It all starts with the letter 'N', all the names of neodymium magnets begin with 'N' for neodymium. The number that follows is a little more technical as this represents the maximum energy product of the magnet in 'Mega-Gauss Oersteds' (MGOe). This is the primary indicator of a magnets 'strength'. In general, higher numbers indicate a stronger magnet.

According to strength of coercive force of sintered neodymium permanent magnet products, products can be classified into different types:
normal coercive force (N), medium coercive force (M), high coercive force (H), super high coercive force (SH), ultra high coercive force (UH), extremely high coercive force (EH) and advanced high (AH).
