Influence of temperature on magnetization. magnetization

You magnets are ferromagnetic materials that have the property of attracting or repelling other magnets. Furthermore, one of the characteristics of materials of this nature (ferromagnetic) is that they magnetize themselves strongly (become magnets) in the presence of a magnetic field.

Experimentally, it is observed that conducting bodies lose all their ferromagnetic properties when heated to certain temperatures. This temperature is characteristic of each material and is called the Curie point.

O Curie point is the limit temperature for the material to remain ferromagnetic. Above that temperature, a material is no longer ferromagnetic and becomes paramagnetic. The materials paramagnetic they are attracted to magnets, however, very weakly.

Do not stop now... There's more after the advertising ;)

Below we have the temperature values ​​of some materials that lose their magnetic properties when subjected to these temperatures:
