摘　　要：利用泰勒展开取近似的方法,给出电偶极子的近似势能,并在自由电偶极子运动规律的基础上,讨论并得出了外磁场下电偶极子的运动规律:外磁场下电偶极子在径向做圆周运动,在切向做简谐振动,整体轨迹为不规则的螺旋式运动.This article negative ions. Using erg lts Yo dy di th scusses the interaction energy of the electric dipole that consisted of positive and e method of Taylor expansion, give the electric dipole＇s approximation potential en Based on the motion rules of free electric dipole, analyze the electric dipole＇s motion rules and solve namics equation by Newton＇s laws of motion in the external magnetic field . Finally, conclude the e lectric dipole＇s motion rules in the external magnetic field, that is to say, the electric dipole respectively does circular motion in radial of the eternal magnetic field, and does the simple harmonic oscillattion in tangential, whose overall trajectory is irregular spiral movement
