摘要
利用铅蓄电池、旋钮式调压器和数字式电流表等器件改进了安培力演示实验,改进后的实验装置能够定量地探究了安培力F与磁感应强度B、电流I。
Some devices,such as lead battery,knob-type voltage regulator,and digital amperemeter were used in Ampere force demonstration experiment.The improved experimental device could quantitatively explore the relationship between Ampere＇s force Fand magnetic induction B,current I,wire length l and angleθbetween Band I.
