Abstract :
A superconducting levitation system was constructed to study the static and dynamic forces exerted by magnetic fields on superconductors. The system produces a 5-T uniform magnetic field and less than 1 T/cm uniform gradient in the static mode. The gradient may also be pulsed with a switching time of less than 0.1 s. In measuring dynamic properties, the displacements of the freely suspended samples were monitored inductively in order to obtain the magnitude of the magnetic force. Control and data acquisition were accomplished by means of an IEEE-488 interface and 9-μm analog-to-digital converter (ADC), using a 80386-based personal computer
