Curie temperature is the temperature above which:

Nickel shows ferromagnetic property at room temperature. If the temperature is increased beyond Curie temperature,then it will show

Assertion: Ferromagnetic substances become paramagnetic above the Curie temperature.
Reason: Domains are destroyed at high temperature.

$A$ soft ferromagnetic material is placed in an external magnetic field. The magnetic domains:

Consider the following statements regarding paramagnetic substances:
$A$. They are weakly attracted by an external magnetic field.
$B$. They are strongly attracted by an external magnetic field.
$C$. Their magnetic susceptibility $(\chi)$ is small and positive.
$D$. In a non-uniform magnetic field, they move from a region of strong magnetic field to a region of weak magnetic field.
Which of the above statements are correct?

From a molecular viewpoint,discuss the temperature dependence of susceptibility for diamagnetism,paramagnetism,and ferromagnetism.
