What is the Difference between N35 and N52 Magnets?

What are N35 and N52 magnets? Seen from their grade strings, both of them are sintered neodymium iron boron (NdFeB) magnets. These two magnets have the same intrinsic coercivity Hcj level higher than 12 kOe (in CGS unit) or 955 kA/m (in SI unit). It is also obviously seen that their maximum energy product (BH)max are around 35 and 52 MGOe, respectively. This huge difference means that the N52 magnets have around 49% more energy than that of the N35… Read More
