Diamagnetic substances are

$A$ soft ferromagnetic material is placed in an external magnetic field. The magnetic domains:

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:

The variation of the intensity of magnetisation $(I)$ with respect to the magnetising field $(H)$ in a diamagnetic substance is described by the graph

Given below are two statements:
Statement $I:$ For a diamagnetic substance $-1 \leq \chi < 0$,where $\chi$ is the magnetic susceptibility.
Statement $II:$ Diamagnetic substances,when placed in an external non-uniform magnetic field,tend to move from the stronger to the weaker part of the field.
In the light of the above statements,choose the correct answer from the options given below.

For protecting a sensitive equipment from the external magnetic field,it should be
