A method and apparatus for the continuous, contactless testing of a long conductor which consists at least partially of superconductive material in which the conductor is moved, with the superconductive material in the superconducting state, through an external magnetic field which induces shielding currents in the superconductive material, while the magnetic field produced by these shielding currents is measured.

A continuously operating superconducting magnetic separator for the segregated separation of particles with different magnetic susceptibility from a mixture such as a mixture of ferromagnetic and non-ferromagnetic ore and rock, in which the magnetic separator comprises a stationary superconducting magnet arrangement along with at least one carrier running through the magnetic field for the particles to be separated, which particles are moved by means of a conveyer chute through the magnetic field of large volume and past the carrier, which is in the form of a ferromagnetic grid, generating a field gradient and forcing the particles onto the grid, from which they are carried to appropriate collection devices.
