1·The experiment verification is made by using the Helmholtz coil.

采用亥姆霍兹线圈进行了试验验证。

2·A Helmholtz coil is installed on the base sliding block through the coil fixed plate and can slide freely on the base guide rail.

亥姆霍兹线圈通过线圈固定板安装在底座滑块上，可以自由的在底座导轨上滑动。

3·In this paper, a triple-coil magnetic field is designed, which is better than Helmholtz coil not only in uniformity but in intensity.

通过研究与比较单线圈、亥姆霍兹线圈、三线圈的磁场，得出三线圈的磁场在均匀性和强度上均超过了单线圈和亥姆霍兹线圈。

4·Has analyzed the Helmholtz coil center region axial magnetic field distribution, gave one kind to survey the Helmholtz coil magnetic field distributed one new method.

分析了亥姆霍兹线圈中心区域轴向磁场的分布，给出了一种测量亥姆霍兹线圈磁场分布的一种新方法。

5·Using the slider to drive a metal bar to cut perpendicularly the uniform magnetic field in the center of a Helmholtz coil, induction electromotive force could be produced.

利用滑块带动金属杆切割亥姆霍兹线圈中心区域匀强磁场的磁感应线，可以产生感应电动势。

6·Abstract: Degree of homogeneity is introduced, thereafter the magnetic field of Helmholtz coil is studied, and the best conditions of this coil is investigated by computer.
