The magnetic susceptibility of a paramagnetic substance is:

There are four light-weight rod samples $A, B, C, D$ separately suspended by threads. $A$ bar magnet is slowly brought near each sample and the following observations are noted:
$(i)$ $A$ is feebly repelled
$(ii)$ $B$ is feebly attracted
$(iii)$ $C$ is strongly attracted
$(iv)$ $D$ remains unaffected
Which one of the following is true?

$A$ thin,lightweight rod of a diamagnetic substance,such as silver,is suspended in a uniform external magnetic field. It will align itself with its length:

If a diamagnetic substance is brought near the north or south pole of a bar magnet,it is:

Among the following properties describing diamagnetism, identify the property that is wrongly stated.
