我们试图通过增加第三个相同半径的串联线圈来改进亥姆霍兹线圈。在这种三线圈阵列中，从外部线圈到中心线圈的距离是线圈半径的0.760倍，中心线圈与外部线圈的圈数之比恰好是59比111。数值结果表明，改进后的亥姆霍兹线圈的磁场均匀区域比亥姆霍兹线圈和麦克斯韦三种线圈的磁场均匀区域大。(C)2002年美国物理研究所。
We attempt to improve the Helmholtz coil by adding a third coil with the same radius connected in series. In this three-coil array, the distance from the outside coils to the central coil is 0.760 times radius of the coils, and the ratio of the number of turns, central to the outside, is exactly 59 to 111. Numerical results demonstrate that the uniform region of magnetic field in the improved Helmholtz coil is larger than that of the Helmholtz coil and of Maxwell's tricoil.
