Actually I recently started learning about ferromagnetism and I encountered this in Wikipedia article Magnetic hysteresis:
The phenomenon of hysteresis in ferromagnetic materials is the result of two effects: rotation of magnetization and changes in size or number of magnetic domains.
The article is about magnetic hysteresis and it explains what causes hysteresis in the ferromagnetic material.
Can you please explain what does rotating of magnetization mean? Does that mean rotation of Magnetization function in the hysterian loop?
(I'm really confused now. Please apologise me if i made a serious error or the question is so stupid.)
