Have you ever considered

 superconductivity might be a frozen magnetism (effect)

 in the cooling fluid,

 around a (super)conductor (catalyst)?

 E.g. The cooling fluid has frozen magnetism

 around near the superconductor surface.

That (surface) acts as a catalyst

 or seed starter for magnetism (domains).

The effect is external to the conductor, not internal;

 & it is (very strongly) magnetic

 on the outside of the conductor.

The superconductor's surface acts as a catalyst

 to kickstart the magnetic fluid's field,

 dealing with frozen magnetism

 in a cold fluid,

 requiring different temperatures for various superconducting metal's surfaces.

E.g. Normal non_magnetic materials

 such as fluids

 can be magnetized at lower temperatures

 with the appropriate catalyst surface

 & current thru the catalyst.

It's a magnetic conduction

 outside of the wire (in the fluid)

 (similar to a high frequency skin effect;

 & larger conduction path around the wire

 having less impedance

 due to more conduction volume

 thru the fluid, around the conductor).

 

Default answer is: no.

 

I suggest that

 because when the temperature is raised,

 the apparatus explodes.
