为什么磁悬浮列车能够浮起来?

在众多高新科技的列车中,磁悬浮列车运行是最与众不同的。它不是jin贴着钢轨行驶,而是悬浮在轨面上飞驰。它不仅速度快,而且安全、平稳、无震动、无污染。磁悬浮列车和超导技术联系jin密。科学家发现,chu1在超导状态的wu质,ju有完全导电xing和安全抗磁xing。超导ti的完全抗磁xing,会对磁铁产生向上的斥力,磁铁于是便会悬空飘浮。磁悬浮列车就是利用这一原理,将超导磁ti安装在列车底bu,轨dao则铺设连续的良导ti薄板。电liu从超导ti中liu过时,产生磁场,形成向下的推力,当推力与车辆重力平衡时,车辆就可悬浮在轨dao上方。悬浮的车ti与轨dao间没有机械接chu2和moca,所以运行时无震动、无污染,也不会脱轨,而且行车速度也可以大大提高。
