What are ferromagnetic materials ? Give examples. What happens to a ferromagnetic material at curie temperature ?

Explanation

Magnetization of ferromagnetic materials is attained by two processes on domains that take place simultaneously. One of them is the rotation of magnetic moment vectors and the other is the increase in the size of domains parallel to the applied field. In paramagnetic materials, magnetization is done only because of the rotation of dipole moments. It is due to domain characteristic of a ferromagnetic material that it is strongly magnetised.
