摘要

Single grained high temperature superconductor (HTS) bulks can trap a magnetic field up to approximately 17 tesla at low temperatures, which is significantly larger than that of permanent magnets (PMs) at about 0.5-1.0 tesla. This study compared the trajectory of magnetic particles using three different magnetic field sources, i.e., an HTS bulk working at 65K and 77 K and a PM, respectively. In addition, the theoretical trajectory of magnetic particles was also calculated and compared with that of the direct experimental observations, which indicated high calculation accuracy. Due to the magnetic flux density gradient differences between a PM and HTS bulk, the distributions of the magnetic particles were also different, which showed the highest density at the edge for a PM and at the center for an HTS bulk. In this report, it was shown that the HTS bulk working at 65 K resulted in a higher magnetic force that can concentrate more magnetic particles in a small area.
