The soft-iron is a suitable material for making an electromagnet. This is because soft-iron has

An example of a diamagnetic substance is

$A$ ball of superconducting material is dipped in liquid nitrogen and placed near a bar magnet.
$(i)$ In which direction will it move?
$(ii)$ What will be the direction of its magnetic moment?

Three identical bars $A, B$ and $C$ are made of different magnetic materials. When kept in a uniform magnetic field,the field lines around them look as follows: Make the correspondence of these bars with their material being diamagnetic $(D)$,ferromagnetic $(F)$ and paramagnetic $(P)$.

The material of a permanent magnet has:

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