多圈共轴线圈产生错位对激励磁场的影响
Effects of Dislocation of MultiPle Coaxial Coils on Magnetic Field
摘要
Abstract
The magnetic field distribution varies with the dislocation of multiple coaxial coils. The basic Biot-Savart Law and the superposition theorem is applied to work out the calculation formulas of the magnetic field. Furthermore,the numerical solution of the variation magnetic induction were calculated using MATLAB,and the field plots were drew. Based on these,the effects of the coil winding rules on the magnetic field distribution is judged and reasonable theory suggests about the magnetic field incentive is given. Calculation results show that the variation of axial magnetic induction is the order of 10—11 T,and the relative change of magnetic field on center plan is less than 1%,while the ration of coil offset and average radius is not more than 0. 04.关键词
