The variation of magnetic susceptibility $\left( \chi \right)$ with absolute temperature $T$ for a ferromagnetic material is given in the figure by:

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

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:

Given below are two statements:
Statement-$I$: Susceptibilities of paramagnetic and ferromagnetic substances increase with decrease in temperature.
Statement-$II$: Diamagnetism is a result of orbital motions of electrons developing magnetic moments opposite to the applied magnetic field.
Choose the $CORRECT$ answer from the options given below:

For two types of magnetic materials $A$ and $B$, the variation of $\frac{1}{\chi}$ ($\chi$: magnetic susceptibility) versus temperature $T$ is shown in the figure. Then:

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