Answer: towards the weaker field region.
- A towards the stronger field region
- B along the field lines only
- C perpendicular to the field
- D towards the weaker field region
Correct answer: D. towards the weaker field region
Explanation: Diamagnetic materials are weakly repelled by magnetic fields, so they migrate from stronger toward weaker field regions.

Concept context
Bar magnets, Earth's magnetism, and how different materials respond to an external magnetic field - diamagnetic, paramagnetic, and ferromagnetic behaviour.
