历届高中物理课本中均有安培定则、左手定则和右手定则的教学内容 ,学生学完这三个定则后往往将其混淆 ,或由于不细心导致错误 ,而对于需要运用两个以上定则处理的复杂物理过程 ,更是感到迷茫 .为了帮助同学们正确综合运用三个定则 ,本文将三个定则列表进行对比 (如表 1所示 ) All previous high school physics textbooks contained teaching contents of the Ampere Rules, left-hand rules, and right-hand rules. Students often confuse them after they finish studying the three rules, or because they do not carefully lead to mistakes, they need to use more than two items. The complex physics process that the rule handles is even more confused. To help students use the three rules correctly, this paper compares the three regular rules (as shown in Table 1).
