| 摘 要： | 提出一种获得均匀磁场的新方法,即将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Helmho ltz线圈磁场的简单公式,对公式的分析表明,改进型Helmholtz线圈的均匀磁场区比Helmho ltz线圈大得多.

| Abstract: | A new method to get uniform magnetic field-improved Helmholtz coils is proposed by replacing Helmholtz coils by three coils with the same radius connected in series. Simple formulas are derved for the magnetic field of the improved Helmholtz coils. Numerical results demonstrate that the uniform region of magnetic field for the improved Helmholtz coils is larger than that of Helmholtz coils. |
