I say "relatively" Because charged particles will experience a retarding force if they travel along magnetic field lines that converge.
我说“比较”，是因为当带电粒子沿著逐渐汇聚的磁力线方向运动时，会感受到一股迟滞力。
Evidently fixed limits exist as regards increase of mass and reduction of retarding force, but the impelling force can be increased indefinitely.
显然，固定的界限只存在于增加质量和减少减速力上，但推动力可以不确定地增加。
