If a diamagnetic solution is poured into a $U-$ tube and one arm of this $U-$ tube is placed between the poles of a strong magnet with the meniscus in line with the field,then the level of the solution will:

If a ferromagnetic material is inserted in a current-carrying solenoid,the magnetic field of the solenoid

Substances in which the magnetic moment of a single atom is not zero are known as:

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 following graph shows the response of magnetization $M$ of a paramagnetic material to the applied magnetic field strength $H$ for three different temperatures $T_1$,$T_2$,and $T_3$. Which of the following is correct?

Given below are two statements: one is labelled as Assertion $(A)$ and the other is labelled as Reason $(R)$. Consider a ferromagnetic material:
Assertion $(A)$: The individual atoms in a ferromagnetic material possess a magnetic dipole moment and interact with one another in such a way that they spontaneously align themselves forming domains.
Reason $(R)$: At high enough temperature, the domain structure of a ferromagnetic material disintegrates. Thus, magnetization will disappear at a high enough temperature known as the Curie temperature.
In the light of the above statements, choose the correct answer from the options given below:
