Spin Offsetting Charge: How Electrons Balance Out

[Cobalt101]

As I understand, two electrons may be found (close) together providing they are of opposite spin. How does this occur ? How does the character of opposite spin offset the impact of the electromagnetic force repelling these two particles of the same charge ?

It doesn't. The result is that the wave function for two electrons with anti-parallel spin has a higher energy than the corresponding wave function with parallel spins, where the electrons will avoid each other because of spin correlation.

How about under superconductivity conditions ? In which electrons "pair up" ?
