Liquid oxygen remains suspended between two pole faces of a magnet because it is

Given below are two statements:
Statement-$I$: Susceptibilities of paramagnetic and ferromagnetic substances increase with decrease in temperature.
Statement-$II$: Diamagnetism is a result of orbital motions of electrons developing magnetic moments opposite to the applied magnetic field.
Choose the $CORRECT$ answer from the options given below:

When a magnetic substance is heated,then it

The variation of magnetic susceptibility $(\chi)$ with magnetising field $(H)$ for a paramagnetic substance is represented by which of the following graphs?

What is the magnetic susceptibility of a superconductor?

$A$ paramagnetic sample shows a net magnetisation of $6 \, A/m$ when it is placed in an external magnetic field of $0.4 \, T$ at a temperature of $4 \, K$. When the sample is placed in an external magnetic field of $0.3 \, T$ at a temperature of $24 \, K$,then the magnetisation will be $...... \, A/m$.
