摘　　要：根据理想"平行导轨模型"的物理特点,运用牛顿第二定律,采用矢量与坐标相结合的方法,对电磁感应中的电感负载平行导轨模型的各种情况进行了计算,计算出了各种情况下的金属杆运动的数学表达式.结果与实践吻合.According to physical character of ideal parallel tracks model in electromagnetic induction, based on Newton second law, ways of combining vector with coordinate have been used to set down all sorts of problems about parallel tracks model with inductance loading. And maths expression of metal rod movement under uarious conditions have been derived. The expressions are in good agreement with pracrice.
