Q189 / 240 · KCET 2026 · Physics
If a paramagnetic bar is brought near a bar magnet, then it is
- Correct answerAAttracted by both the poles of the bar magnet
- BRepelled by both the poles of the bar magnet
- CAttracted by the South-pole and repelled by the North-pole of the bar magnet
- DAttracted by the North-pole and repelled by the South-pole of the bar magnet
Solution
Paramagnetic materials have a tendency to move from a region of weak magnetic field to a region of strong magnetic field.
When a paramagnetic bar is brought near either pole of a bar magnet, it gets weakly magnetized in the direction of the external magnetic field.
This induced magnetization causes the near end of the bar to develop an opposite magnetic polarity to that of the adjacent pole of the bar magnet.
Therefore, the paramagnetic bar is attracted by both the North and South poles of the bar magnet.
Answer: Attracted by both the poles of the bar magnet
When a paramagnetic bar is brought near either pole of a bar magnet, it gets weakly magnetized in the direction of the external magnetic field.
This induced magnetization causes the near end of the bar to develop an opposite magnetic polarity to that of the adjacent pole of the bar magnet.
Therefore, the paramagnetic bar is attracted by both the North and South poles of the bar magnet.
Answer: Attracted by both the poles of the bar magnet
Hence, the correct answer is option: 'A'.
