摘　　要：利用单盘天平、磁极、教学用的电表、变阻器等器材自制了安培力定量演示装置.该装置通过单盘天平可计算出安培力,并与电流计所示值及裸导线长度做比较,得出定量的结论.The device quantitatively demonstrating Ampere force consists of single beam balance, magnet, ammeter, and rheostat. Utilizing a single beam balance, Ampgère force can be calculated. Comparing with the reading of ammeter and the length of the bare wire, quantitative conclusion is obtained.
