The transmission of electricity itself generates a magnetic field. for an electron moving in a particular direction, a 90-degree magnetic force is emitted.

Try winding some copper around a nail and connecting the wires to a battery. You'll be able to pick up paperclips.

Superconductivity allows current levels to get high enough to generate massive magnetic fields so I don't think there's a difference.

but then I'm no particle physisict

I think AstralStorm was referring to flux pinning.
