Some questions on superconductors

[roshan2004]

Here are some questions on superconductors that I would like ask-
The first one is What are the differences between superconductors and infinite conductors?

 

[element4]

What is a infinite conductor? Do you mean a perfect conductor (zero resistivity)?

In that case, the difference is that a superconductor is a perfect conductor that is also a perfect diamagnet (the Meissner effect).

A perfect conductor would trap magnetic flux, while a superconductor expels magnetic flux.
