A super conductor is characterised by-
|
|
Low permeability
|
|
|
Infinite permeability
|
|
|
Zero permeability
|
|
|
High permeability
|
Explanation:
Detailed explanation-1: -Super conductors are the materials that conduct electricity with zero resistance. ⇒ Zero resistance means Zero resistivity ∴ Conductivity is infinity. Hence the correct option is option B.
Detailed explanation-2: -So, the superconductivity state cannot exist in the presence of a magnetic field greater than a critical value, even at absolute zero.
