High density MgB/sub 2/ bulk materials of different grains size: supercurrents instability and losses in variable magnetic fields

The bulk MgB/sub 2/ material shows very promising characteristics to be applied in many AC devices, i.e. as electric motors, as magnetic field screening apparatus or as variable inductor or resistor for Fault Current Limitation. In all these cases the evaluation of supercurrents persistency and of t...
