When a magnetic substance is heated,then it

$A$ diamagnetic liquid is filled in a $U$-tube. One arm of the $U$-tube is placed in an external magnetic field with the meniscus in line with the field. The level of the liquid in that arm will

The materials having negative magnetic susceptibility are

Consider the following two statements $A$ and $B$ and identify the correct choice in the given answers.
$A$. Paramagnetism is explained by domain theory.
$B$. Susceptibility of a diamagnetic substance is independent of temperature.

The magnetic susceptibility of an ideal diamagnetic substance is

Suppose a small cylinder of a paramagnetic substance and a small cylinder of a diamagnetic substance are placed between the (parallel) pole pieces of a strong magnet,so that they are aligned along the direction of the field lines. Will they attract or repel each other?
