Are 45sh and N45 the same magnet?

Are 45sh and N45 the same magnet? I saw that some netizens asked this question. I think there must be a large number of friends who don't know, so the following

Let's introduce it.

Are 45sh and N45 the same magnet?

Not only N45, but also 45h and 45sh. They are all made of the same material, that is, neodymium iron boron magnet and rare earth magnet.

45sh and N45 are magnetic forces. Which is stronger?

When the specifications are the same, their magnetic force is the same. The main difference is that the coercivity is different. The permanent magnet with higher coercivity means that it has stronger magnetic force

Anti demagnetization capability, including magnetic field demagnetization and thermal demagnetization. We can understand that the temperature resistance is different. For example, N45 can only withstand temperature of 80 degrees. There are certain requirements for magnetic force, but there are no requirements

It needs high temperature resistant normal temperature environment, 45sh can withstand 150 degrees, and is more used in motor and other fields.
