                磁悬浮风车课程课件

 

    大家都知道磁悬浮列车利用磁场“同性相斥”的原理,让列车具有抗拒地心引力的能力,使车体完全脱离轨道,悬浮在距离轨道约1厘米处,腾空行驶,创造了近乎“零高度”空间飞行的奇迹。本节实验也正是利用这个原理能把笔悬浮起来。是不是感觉很神奇呢?大家试试看能不能让笔悬浮起来。

实验目的:1.利用磁铁同性相斥的作用力
               2.了解磁悬浮简单的原理
实验认知:
            ABS构件:磁悬浮风向标整体支撑结构
            磁 铁:磁铁能够产生磁场,具有吸引铁磁性物质如铁、镍、钴等金属的特性。

实验报告:
磁极:磁铁上磁性强的部分叫磁极。磁体周围存在磁场,磁体间的相互作用就是以磁场作为媒介的。一个磁体无论任何时候都有两个磁极,可以在水平面内自由转动的磁体,静止时总是一个磁极指向南方,另一个磁极指向北方,指向南的叫做南极(S极),指向北的叫做北极(N极)。同性磁极相互排斥、异性磁极相互吸引。41
