Levitation force between permanent magnets and a high Tc superconductor (HTSC) is analyzed numerically based on the critical state model. Size and combination of the magnets are examined to obtain the large levitation force. An axisymmetric code is applied to the evaluation of basic properties of the levitation force, and a thin plate approximation code is applied to the analysis of a partial model of a flywheel. There are the size of the magnets and the magnetic field configuration to obtain the maximum levitation force for a given size of the HTSC. Obtained results will be useful to design the flywheel system with HTSC.
