ABSTRACT:
A device for producing a uniform, parallel, intensity-variable magnetic field includes at least one coil and/or permanent magnet for producing a magnetic field, and a cylinder which contains a superconductor and which has a slit extending parallel to its axial direction. The axis of the coil and/or the permanent magnet and the axis of the cylinder are parallel to each other. The superconductor is a type II superconductor which has a critical current density not equal to zero under a magnetic field higher than its lower critical magnetic field. Furthermore, the cylinder may comprise several superconductor sheets joined together into a cylindrical shape or a superconductor-containing sheet which is wound spirally about itself or is rolled up several times about itself in the form of a hollow cylinder.
