Options

A. Diamagnetism is due to difference in magnetic moments of paired electrons in presence of external magnetic field.
B. Property of diamagnetism occurs in all materials.
C. Magnetic field due to induced magnetic moment is opposite to external field applied.
D. Intensity of magnetization of paramagnetic materials is proportional to magnetizing field intensity.

Answer

A, B, C, D

Explanation

Property of diamagnetism occurs in all materials. When diamagnetic material is kept in external magnetic field then a magnetic moment is induced in it along opposite direction of applied field. External field causes change in spin of paired electrons in such a manner that net magnetic moment is induced opposite to applied field. Intensity of magnetization of paramagnetic material is proportional to the magnetizing field intensity and proportionality constant is called magnetic susceptibility of the material.
