Question:
Rods 'A', 'B' and 'C' are made of a paramagnetic, a ferromagnetic and a diamagnetic substance respectively. A magnet is brought close to them, it will
Rods 'A', 'B' and 'C' are made of a paramagnetic, a ferromagnetic and a diamagnetic substance respectively. A magnet is brought close to them, it will
Show Hint
- Ferro $>$ Para (attraction strength)
- Diamagnetic always repelled
Updated On: May 4, 2026
- repel all three substances.
- attract ' A ' strongly, ' B ' weakly and repel 'C' weakly.
- attract ' A ' strongly but repel both ' B ' and 'C' weakly.
- attract ' A ' weakly, ' B ' strongly and repel 'C' weakly.
Show Solution
Verified By Collegedunia
The Correct Option is D
Solution and Explanation
Concept:
Magnetic behavior of materials:
• Paramagnetic: weakly attracted
• Ferromagnetic: strongly attracted
• Diamagnetic: weakly repelled
Step 1: Identify materials.
• A $\rightarrow$ paramagnetic
• B $\rightarrow$ ferromagnetic
• C $\rightarrow$ diamagnetic
Step 2: Apply behavior.
• A $\rightarrow$ weak attraction
• B $\rightarrow$ strong attraction
• C $\rightarrow$ weak repulsion
Step 3: Match option.
\[ \text{Correct option is (D)} \]
