The most exotic diamagnetic materials are

The variation of magnetic susceptibility with the temperature of a ferromagnetic material can be plotted as

The Curie-Weiss law is obeyed by iron at a temperature ......

The meniscus of a liquid contained in one of the limbs of a $U-$tube is placed between the poles of an electromagnet with the meniscus in line with the field. The liquid is seen to rise in the limb by a small amount. This indicates that the liquid is:

$A$ uniform magnetic field,parallel to the plane of the paper,exists in space and is 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:

Assertion: Ferromagnetic substances become paramagnetic above the Curie temperature.
Reason: Domains are destroyed at high temperature.
