If you have: A Linear Induction Coilgun, basically like a series of Induction Furnaces, using copper coils with high AC current at a high frequency. Where the projectile travelling inside those coils has a shorted superconducting coil around the outside of it, embedded in the ceramic projectile casing. A) Will the projectiles superconducting wire get hot? I would assume not since there is no resistance. B) Will metallic components or distilled water inside the projectile (within the superconducting coil) get currents induced in them or get hot? I would assume not since the superconducting coil is shielding them like a Faraday cage. See attached image.
