$A$ 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?

Among the following, for which substance does the magnetic susceptibility not depend on the temperature?

Consider the regular array of vertical identical current-carrying wires (with the direction of current flow as indicated in the figure alongside) protruding through a horizontal table. If we scatter some diamagnetic particles on the table,then they are likely to accumulate:

What are the two reasons for using soft iron as the material for electromagnets?

There are four light-weight rod samples $A, B, C, D$ separately suspended by threads. $A$ bar magnet is slowly brought near each sample and the following observations are noted:
$(i)$ $A$ is feebly repelled
$(ii)$ $B$ is feebly attracted
$(iii)$ $C$ is strongly attracted
$(iv)$ $D$ remains unaffected
Which one of the following is true?
