摘　　要：文章分析了电与磁的关系,应用电磁驱动基本原理,通过物理理论推导证明了驱动磁动力小火车运动的力是安培力,是磁铁表面环形等效电流在通电螺线管产生磁场中受到的力。研究磁动力小火车实验的可行性,分析磁动力小火车的运行原理,研究出相关参量对小火车速度和功率的影响。This paper reveals the close relationship between electricity and magnetism as well as the basic principle of electromagnetic drive.Through detailed physical theory derivation,experimenter proved that the driving force of the electromagnetic train is Amber force on the magnet equivalent current when the train was placed inside the electric solenoid magnetic field.Additionally,the influence of some parameters,like copper wire diameter,on the speed of electromagnetic train is analyzed.

关 键 词：磁动力小火车 安培力 驱动原理
