When a diamagnetic material is placed in an external magnetic field the spin motion of electrons is so modified that the electrons which produce the moments in the direction of the external field show down while the electrons which produce magnetic moments in opposite directions get accelerated.
Thus, a net magnetic moment is induced in the opposite direction of the applied magnetic field. Hence the substance is magnetized opposite of the external field. Thus, it moves from stronger. Weaker parts of the magnetic.

Diamagnetic substances are those which have a tendency to move from stronger to the weaker part of an external magnetic field. Let's understand why option 'A' is the correct answer by breaking down the characteristics of diamagnetic substances.
Explanation:
1. Diamagnetic Substances: Diamagnetic substances are materials that exhibit a weak repulsion when placed in an external magnetic field. This is due to the induced magnetic moments in the opposite direction to the applied magnetic field.
2. Weak Repulsion: Diamagnetic substances are repelled by both the north and south poles of a magnet. However, this repulsion is quite weak compared to other types of magnetism. In the presence of an external magnetic field, diamagnetic substances tend to move from stronger to weaker parts of the field.
3. Induced Magnetic Moments: When a diamagnetic substance is placed in an external magnetic field, the magnetic moments of the atoms or molecules in the material align in the opposite direction to the applied field. This creates a net magnetic moment in the direction opposite to the applied field.
4. Weaker to Stronger Part: Due to the induced magnetic moments, diamagnetic substances experience a force that pushes them away from regions of stronger magnetic field towards regions of weaker magnetic field. This is because the induced magnetic moments repel the external magnetic field.
5. Examples of Diamagnetic Substances: Some common examples of diamagnetic substances include water, wood, plastic, copper, gold, and most organic compounds. These substances have filled electron shells and do not possess any unpaired electrons, which makes them diamagnetic.
In summary, diamagnetic substances tend to move from stronger to the weaker part of an external magnetic field. This is due to the weak repulsion they experience when placed in a magnetic field, caused by the induced magnetic moments in the opposite direction to the applied field.
