摘要
提出将Helmholtz线圈改为 3个同半径的串联线圈 ,以得到改进型的Helmholtz线圈 .经计算得到了改进型Helmholtz线圈磁场的简单公式 ,对公式的分析表明
An improved Helmholtz coil is designed by replacing Helmholtz coil with three coils with the same radius connected in series.Simple formulas are derived for the magnetic field of the improved Helmholtz coil.Numerical results demonstrate that the uniform region of magnetic field for the improved Helmholtz coil is larger than that of Helmholtz coil.
