The magnetic susceptibility of a diamagnetic substance:

The Curie temperature $T_{C}$ represents:

$A$ 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?

Which one of the following characteristics is not associated with a ferromagnetic material?

$A$ small bar of ferromagnetic substance is placed in a non-uniform magnetic field. In which direction does it move?

The Curie temperatures of cobalt and iron are $1400 \,K$ and $1000 \,K$ respectively. At $T=1600 \,K$, the ratio of the magnetic susceptibility of cobalt to that of iron is
