Table 6.3 lists the levitation forces (N) of different seven-block YBCO samples. The
levitation force of 7 YBCO in array 8 over PMG was 264.1 N at 10-mm gap and
the total levitation force of 7-block-alone YBCO was 500.6 N at 10-mm gap [24].
The total levitation force of array 8 was smaller than the sum of the levitati-
on forces of the seven single pieces of YBCO, since four pieces in array 8 were
not placed at the center position along the PMG lengthways direction. In order
to get the optimum levitation force of the system, selecting array 8 was more
appropriate.
