Consider the following statements: Superconductivity in a material can be destroyed by
1. increasing the temperature above a certain limit.
2. applying a magnetic field above a certain limit.
3. passing a current, above a certain limit, through the material.
4. increasing the current to a point above the critical current. Of these the correct statements are:
-
- 2, 3 and 4
- 1, 3 and 4
- 1, 2 and 3
- 1, 2 and 4
Correct Option: D
Superconductivity in a material can be destroyed by—
● Increasing the temperature above a certain limit.
● Applying a magnetic field above a certain limit.
● Increasing the current to a point above the critical current.
