The variation of the intensity of magnetisation $(I)$ with respect to the magnetising field $(H)$ in a diamagnetic substance is described by the graph

$A$ diamagnetic material in a magnetic field moves:

$A$ uniform magnetic field parallel to the plane of paper existed in space,initially directed from left to right. When a bar of soft iron is placed in the field parallel to it,the lines of force passing through it will be represented by which figure?

Identify the false statement regarding the magnetic properties of substances.

$A$ sample of a paramagnetic salt containing $3 \times 10^{24}$ atomic dipoles each of dipole moment $2 \times 10^{-23} \text{ A-m}^2$ is subjected to a uniform magnetic field of $880 \text{ mT}$ and cooled to a temperature of $3.5 \text{ K}$. The degree of magnetic saturation achieved is $10 \%$. If the sample is subjected to a magnetic field of $990 \text{ mT}$ and cooled to a temperature of $2.1 \text{ K}$, then the total dipole moment of the sample is (in $\text{ A-m}^2$)

What is a paramagnetic substance? If a small bar of a paramagnetic substance is placed in a non-uniform magnetic field,in which direction does it move?
