Question

If a paramagnetic bar is brought near a bar magnet, then it is

• A. Attracted by both the poles of the bar magnet
• B. Repelled by both the poles of the bar magnet
• C. Attracted by the South-pole and repelled by the North-pole of the bar magnet
• D. Attracted by the North-pole and repelled by the South-pole of the bar magnet

Hint:

Remember:
- Ferromagnetic: Strongly attracted to both poles.
- Paramagnetic: Weakly attracted to both poles.
- Diamagnetic: Weakly repelled by both poles.

Answer 1

The Correct Option is A

Step 1: Understanding the Question:
The question asks about the magnetic interaction between a paramagnetic material and the poles of a standard permanent bar magnet.
Step 3: Detailed Explanation:
Paramagnetic materials have atoms with permanent magnetic dipoles. When placed in an external magnetic field, these dipoles tend to align themselves in the direction of the external field.
A characteristic property of paramagnetic substances is that they are weakly attracted toward stronger parts of an external magnetic field.
A bar magnet has its strongest field intensity near its poles (both North and South).
Therefore, a paramagnetic bar will experience a weak attractive force when brought near either the North pole or the South pole of a bar magnet.
Step 4: Final Answer:
It is attracted by both the poles of the bar magnet, which is option (1).
