Abstract

We developed the numerical analysis of magnetic force characteristics in high-Tc bulk superconducter. In analysis using the measured Jc, We obtained good agreements with experimental results under different magnet diameter condition. The results show that we obtained anticipation method of magnetic force characteristics of high Tc superconducting bearing. Moreover we evaluated the magnetic force of 1kWhr superconducting flywheel system which arranged plural circular superconductors. It was confirmed good agreement with experimental results. So we will be able to evaluate the magnetic force characteristics of flywheel system without many experimental examinations.
