Question:
Meissner effect is a phenomenon of:
Meissner effect is a phenomenon of:
Show Hint
When a superconductor is cooled below its critical temperature, it expels all magnetic fields, thus demonstrating perfect diamagnetism, which is fundamental to magnetic levitation and many applications in the field of advanced materials.

- Perfect diamagnetism
- Perfect paramagnetism
- Perfect ferromagnetism
- Perfect antiferromagnetism
Hide Solution
Verified By Collegedunia
The Correct Option is A
Solution and Explanation
The Meissner effect describes the expulsion of magnetic fields from a superconductor when it is cooled below its critical temperature. Key features:
• Perfect diamagnetism: Magnetic susceptibility becomes −1.
• Superconducting state: The material transitions to zero electrical resistance.
• Applications: Used in magnetic levitation and superconducting magnets.
