Answer 1

Explanation:

Superconductor:

Superconductors are that material, whose electrical resistance vanishes while lowering the temperature.
The temperature at which it happens is called critical temperature.
Materials which do not allow magnetic flux lines to pass through them is a property of superconductors.
Eg. Diamagnetic material

Material	Magnetic flux behaviour
Diamagnetic	Weakly repelled. Negative susceptibility.
Paramagnetic	Not as strong as ferromagnetic materials, but the attraction is present.
Ferromagnetic	Strongly attracted. Permanent magnet once magnetised.
Anti-ferromagnetic	Neighbouring atomic moments are antiparallel to each other, which leads to a zero-net magnetization.
