  磁悬浮列车的原理其实很简单,在家就能自制一辆“磁悬浮列车”<\/p>

  磁悬浮列车就是利用了磁铁同极相斥,异极相吸的原理,根据磁铁的这个性质,其实我们在家也可以造一列“磁悬浮列车”<\/p>

  只需要,一节干电池,几块强磁铁,一些细铜线<\/p>

  首先来“造电车轨道”,先把铜线缠绕成线圈,就像是弹簧一样,轨道长短根据自己的喜好而定~<\/p>

  之后来制造列车~很简单,把强磁铁吸在电池的两端,磁悬浮列车就制作完毕了!<\/p>

  然后把电池放进铜线圈内~<\/p>

  磁悬浮列车自己就跑起来啦!<\/p>

  原理其实很简单,跟磁悬浮关系不大,只是磁铁和铜线圈之间的摩擦力很小很小,看起来就像悬浮一样。。。。其核心就是利用了电动机的原理,只是把转子和定子反了过来,让线圈固定,而原来的定子磁铁变成了转子,这样就运行了起来。。。<\/p>
