Claim:
1. A pipeline inspection gauge for monitoring the structural integrity of a pipeline by means of the magneto-inductive technique, characterized in that it comprises a superconducting electromagnet suitable for generating a magnetic field comprising a superconductor material, a cryostat suitable for containing and maintaining said superconducting electromagnet at cryogenic temperatures which are below a critical temperature of said superconductor material, said critical temperature being a temperature at which said superconductor material opposes a zero electric resistance, and at least two magnetic conveyors connected to the cryostat, suitable for conveying the magnetic field generated by the superconducting electromagnet to the wall of the pipeline and facilitating the closing of a magnetic circuit, said magnetic conveyors being made of polymeric material and comprising, in their interior, a flexible core made of ferromagnetic material including a bundle or pack of steel wires.
