手动拼装教具系列均不送电池！！电池自备！！谢谢！！！
【奥斯特实验】表明通电导线周围和永磁体周围一样都存在磁场·奥斯特实验揭示了一个十分重要的本质——电流周围存在磁场，电流是电荷定向运动产生的，所以通电导线周围的磁场实质上是运动电荷产生的。显示通电导线周围存在着磁场的实验。如果在直导线附近（导线需要南北放置），放置一枚小磁针，则当导线中有电流通过时，磁针将发生偏转。这一现象由丹麦物理学家奥斯特在1820年7月通过试验发现。从判定电流周围磁场方向的安培定则——右手螺旋定则认识磁场的方向性及磁感线的特征.在此基础上，通过了解环形电流、通电螺线管磁场的磁感线，以及条形磁体和马蹄形磁体磁场的磁感线，进一步认识磁场的方向性。 由于地磁场的存在，要使磁针明显偏离原来方向，导线中需要较强的电流（约5～10安），这样强的电流一般可以采取触接电池两极引起短路获得。因此，实验相当于电源外部短路，电源将受到损坏（干电池内电阻较大，以使用干电池为好）。实验时应向学生说明这仅仅是为了获得短暂的大电流而采取的变通办法。为保护电源，电路中应串联滑动变阻器限流，而且通电时间要短。导线必须南北向放置，如沿东西向放置力矩为零，不偏转。电流的周围存在磁场。磁场方向和电流方向有关。
