Temperature and magnetic flux density

[Tufon]

Hello all; I am new in this forum, currently in High School.

For some time now, I have been looking online for a relationship between temperature and magnetic flux density of a ferromagnet; below the Curie point. However, I can't seem to find any relationship or formula. Do any of you know what kind of relationship this is? Thank you very much!

See particularly posts #2 and #3 of this "link". The students were doing a laboratory experiment on the topic you mentioned. https://www.physicsforums.com/threa...perature-relationship-in-ferromagnets.923380/
