The given figure represents a material which is

$A$ ferromagnetic material is heated above its $Curie$ temperature. Which one is a correct statement?

Curie temperature is the temperature above which

Why is the magnetic susceptibility of diamagnetic materials negative? Explain.

The Curie temperature $T_{C}$ represents:

The variation of intensity of magnetisation $(I)$ and the applied magnetic field intensity $(H)$ for three magnetic materials $X$,$Y$ and $Z$ are shown in the graph as $OX$,$OY$ and $OZ$ respectively. The materials $X$,$Y$ and $Z$ respectively are:
