Yes, superconductivity also involves magnetic field so it is vastly more useful than just lossless transfer of electricity.

Specifically, superconducting electromagnets. Users include particle accelerators, highest end chromatography, MRI and magnetic levitation.

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.
