When it comes to permanent magnets, what kind of magnet do you think of? Neodymium iron boron permanent magnet? Ferrite permanent magnet? Indeed, these two types are relatively easy to come into contact with, but there are still many permanent magnets that many people are not familiar with. Today, we will introduce the magnetic range and characteristics of some permanent magnets to help you understand more.

The following figure shows the magnetic properties range of the main permanent magnets (sintered neodymium iron boron sintered samarium cobalt injection molded isotropic neodymium iron boron injection molded ferrite sintered ferrite bonded neodymium iron boron).
