摘要
研究了双圈环形电流发生错位情况下其在空间激励产生磁场的分布变化，用最基本的毕奥一萨伐尔定律和叠加定理推算出磁场公式，并借助MATLAB软件计算出磁感应强度变化的数值解，画出磁场变化分布图等。由此判断出磁感应线圈缠绕规则性对激励磁场分布的影响，对于一定精度的磁场的产生、保持给出合理的理论建议。计算结果表明，线圈因缠绕规则性等原因引起的细微错位而导致的磁场分布变化在10^（-6）量级以下，对现阶段实际应用磁场的影响是可接受的。
The magnetic field distribution varies with the dislocation of coaxial drive coils. The basic Biot-Savart law and the superposition theorem is applied to work out the calculation formulas of the magnetic field, and with the help of MATLAB the numerical solution of the variation magnetic induction is calculated and the field plots is drawn. Based on these, the effects of the coil winding rules on the magnetic field distribution were judged and reasonable theory suggests is given about the magnetic field incentive and maintenance calculation resuhs show that the effect of dislocation of a double coaxial coil on magnetic field is less than the order of 10-6 that is acceptable to actual application currently.
