Abstract	Experimental results of levitation force of multi-block YBaCuO hulk HTSs over a NdFeB guideway are presented. The magnetic field in the center of the surface of the NdFeB permanent magnet guideway is up to 1.2 T and still 0.4 T at the position of 20 mm above it. Several YBaCuO bulk samples are fixed in a columnar liquid nitrogen vessel with a thin bottom (3.5 mm). The experimental results show that the levitation force is quite different for various combinations of YBaCuO bulks. The otal combination magnetic levitation force of seven blocks of YBaCuO bulk superconductors is 264.1 N when the gap between the YBaCuO HTS and the NdFeB guideway is 10 mm, and levitation force is 167.5 N at 20 mm. Levitation force is even 106.2 N at 30 mm. The optimization of the levitation force of multi-block YBaCuO bulk superconductors is discussed after the authors analyze the experimental data.
