Imagine a superconductive ring with its current being increased by EM induction.
How is current increased microscopically? I see only two possibilities:
1) Increase in the number of moving charges.
2) Increase in the speed of moving charges.
Or some combination of both.
Main question: so how is it?
Let mi ask side questions:
A) Would there be synchrotron radiation from superconducting ring (inwards acceleration of charges)?
B) Could be somebody so kind as to summarize limiting conditions for superconductivity, so far I know about temperature, magnetic field, current density... is there something else?
