Answer 2

Hey !!

The temperature at which a ferromagnetic substance loses its ferromagnetic and attains paramagnetism only is called ''CURIE TEMPERATURE''.

For iron, the curie temperature is 1033 K, for Ni it is 629 K and for Fe₃O₄ it is 850 K. Below this temperature paramagnetic substances behave as ferromagnetic substances.

Hope it helps you !!
