Countermeasures of Lift Force Improvement of Magnetic Levitation System without Control Using High-Tc Superconducting Bulks

  We are studying a magnetic levitation system without control using magnetic shielding effect of high-Tc superconducting bulk. The problem relating to this system is how to increase the lift force without a decline of the stability. We have proposed the two new methods to improve the lift force. One of the new methods is to insert a ferromagnetic plate between the superconductors and the permanent magnet. The other method is to place more than two basic units in parallel. In this study, we mainly examined the lift force numerically.
