“电偏转”和“磁偏转”是分别利用电场和磁场对运动电荷施加作用,从而控制其运动方向的过程;因磁场和电场对电荷的作用具有不同的特征,故使得两种偏转也存在以下几方面的差别:一、受力特征的差别在“磁偏转”中,质量为 m、电荷量为 q 的粒子以速度 v 垂直射入磁感应强度为 B 的匀强磁场中时,所受磁场力(即洛伦兹力)F_B=qvB 与粒子速度 v 相关, “Electrical deflection” and “Magnetic deflection” are processes that use electric and magnetic fields to act on the motion charge, respectively, to control the direction of motion. Because the effects of magnetic fields and electric fields on the charge have different characteristics, they make the two Deflection also has the following differences: First, the difference in stress characteristics In “magnetic deflection”, particles of mass m and charge q are injected into a uniform magnetic field with a magnetic induction intensity B at a vertical velocity v. At the moment, the force of the magnetic field (ie Lorentz force) F_B=qvB is related to the particle velocity v,
