针对质子在磁场中运动聚焦的问题（2010年江苏高考物理第9题），分析了附加磁场的边界形状以及其与原磁场方向的关系，发现附加磁场边界与质子进入磁场速度的方向、附加磁场的大小和方向等有明确关系。对文献[2]中关于附加磁场方向不确定的观点给予否定。

In view of the focus on motion of protons in the magnetic field, this paper analyses question 9 on physics test of Jiangsu College Entrance Examination. Then it makes an analysis and discussion on the boundary shape of the additional magnetic field and its connection with the direction of the original. The result shows that the boundary shape of additional magnetic field is clearly relevant with the incident velocity of the protons, the magnitude and direction of the additional magnetic field. It denies the viewpoint in reference No. 2 that the direction of the additional magnetic field is uncertain and makes a discussion by drawing boundary graphs of the additional magnetic field.
