Question:
Which of the following properties is not observed in the case of Superconductors?
Which of the following properties is not observed in the case of Superconductors?
Show Hint
Superconductors exhibit perfect diamagnetism, not paramagnetism. The Meissner Effect is key!
Updated On: Sep 19, 2025
- Meissner Effect
- Formation of Cooper pairs
- Paramagnetism
- Zero resistivity
Hide Solution
Verified By Collegedunia
The Correct Option is C
Solution and Explanation
Step 1: Superconductivity properties.
Superconductors exhibit several unique behaviors when cooled below their critical temperature: - Meissner Effect: Expulsion of magnetic fields from a superconductor. - Formation of Cooper pairs: Electrons pair up with opposite spin and momentum, enabling superconductivity. - Zero resistivity: Complete absence of electrical resistance. Step 2: Paramagnetism.
- Paramagnetism: Materials that are weakly attracted by an external magnetic field, which is not a property of superconductors. Instead, superconductors are characterized by perfect diamagnetism (expelling the magnetic field).
Final Answer: \[ \boxed{\text{Paramagnetism}} \]
