A major factor in the design of large superconducting magnets is the problem of premature quenching, notably the "training" effect, associated with the use of epoxy resin impregnants. This paper draws attention to the existence of a simple but neglected solution to this problem. A review is given of

✦ Synopsis
Experiments with test coils show that "training" of superconducting magnets is considerably reduced by loading and unloading the conductor at room temperature before winding the magnet. This preload treatment seems to be a simple way of coping with this problem.

For EDS-type magnetically levitated trains, magnetic shielding of stray fields produced by superconducting magnets is an important task. We seek the optimal thickness distribution (configuration) of magnetic material, which is the lightest and keeps the magnetic field at tolerable levels in the vehi
