Talk:Critical field

I came here from Superconductor classification reading about "Type I superconductors". And here is no information about them. let's put it! --Alxmel (talk) 09:37, 29 October 2013 (UTC)
 * I added some! ArthurPSmith (talk) 21:01, 30 January 2014 (UTC)
 * Hi, Someone changed what you added |diff. Is it still correct ? - Rod57 (talk) 19:49, 21 December 2015 (UTC)
 * Thanks for the notification! The change corrected part of what I had said, so it wasn't wrong, but it also introduced a piece about infinitely long wires that didn't make sense. I've fixed it a bit; hope it makes more sense now. ArthurPSmith (talk) 21:59, 22 December 2015 (UTC)

Need diagram
eg the B-T diagram used in Type-II superconductor. - Rod57 (talk) 14:29, 22 December 2015 (UTC)

What is the relation between the critical field and the critical current
It says "direct relation between the critical field and the critical current " - what is the proportionality constant for SC ? - Rod57 (talk) 14:37, 22 December 2015 (UTC)
