Vedclass · Accepted Answer

The susceptibility of a diamagnetic material is a positive quantity.

Vedclass · Answer

(A) The magnetic susceptibility $(\chi)$ of a diamagnetic material is a negative quantity,$(\chi  0)$. Therefore,statement $(A)$ is incorrect.Paramagnetic materials obey Curie's law,which states that susceptibility is inversely proportional to absolute temperature.Ferromagnetic materials consist of small regions called magnetic domains,each containing approximately $10^{17}$ atoms,which act as permanent magnetic dipoles.Soft ferromagnetic materials have low retentivity,meaning their magnetisation disappears easily upon the removal of the external magnetic field.Thus,statement $(A)$ is the incorrect statement.

Identify the incorrect statement from the following.
