Influences of cooling height and lateral moving speed on the levitation characteristics of YBaCuO bulks

Using an updated high-temperature superconductor (HTS) maglev measurement system, electromagnetic forces between a YBaCuO bulk superconductor and a permanent magnet (PM) have been measured under different cooling height (CH) and different lateral moving speed of the PM. It is found that the influence of the moving speed on both the levitation and lateral force is substantial and as such the results shown in this work are a benefit to the understanding of levitation systems.
