图5 (a)鞍形线圈与(b)亥姆霍兹线圈仿真. 圆柱体内颜色由蓝到红表示磁感应强度（μT）由弱到强. 鞍形线圈磁场沿y方向，亥姆霍兹线圈磁场沿z方向

Fig. 5 (a) Simulation of the saddle coil and (b) Helmholtz coil. The color gradient from blue to red within the cylinder represents the magnetic flux density (μT) increasing from weak to strong. The magnetic field direction of the saddle coil is along the y-axis, while that of the Helmholtz coil is along the z-axis
