Ferromagnetism

Introduction
-
-
Causes permanent magnets to attract through opposites poles as well as repels when same poles facing each other
-
Temperature Dependence
Below Curie temperature, the spins are of the same magnitude and well ordered
One it reaches Curie temperature, moments become randomly aligned, mean that spin-coupling limit has surpassed. Thus causing coupling to break down
When above Curie temperature, it becomes paramagnetic
