Dia, Para and Ferromagnetism on the Basis of Domain Theory

Which one of the following species is diamagnetic in nature?

Given below are two statements:

Statement I : The diamagnetic property depends on temperature.

Statement II : The induced magnetic dipole moment in a diamagnetic sample is always opposite to the magnetising field.

In the light of given statements, choose the correct answer from the options given below

Given below are two statements:

Statement I: For diamagnetic substance $-1\le \mathrm{x}<0$, where $\mathrm{x}$ is the magnetic susceptibility.

Statement II: Diamagnetic substance when placed in an external magnetic field, tend to move from stronger to weaker part of the field. In the light of the above statements, choose the correct answer from the options give below.

Consider two statements:

S1: Magnetic susceptibility of diamagnetic substance is $-1\le \chi <0$.

S2: Diamagnetic substance moves from stronger to weaker magnetic field.
