磁偏转与电偏转分别是利用磁场和电场对运动电荷施加作用,控制其运动方向.这两种偏转有如下差别:1.受力特征在磁偏转中,质量为m,电荷量为q的粒子以速度v垂直射人磁感应强度为B的匀强磁场中,所受磁场力(即洛伦兹力)FB=Bqv.FB使粒子的速度方向发生变化,而速度方向的变化反过来又使FB的方向变化,FB是变力.
Magnetic deflection and electric deflection are the use of magnetic field and electric field to exert motion on the motion charge and control the direction of motion. These two kinds of deflection have the following differences: 1. Force characteristics In the magnetic deflection, the mass is m, the particle with the charge quantity q In a uniform magnetic field with a velocity v perpendicularly projecting the magnetic induction intensity B, the force of the applied magnetic field (ie Lorentz force) FB=Bqv.FB changes the direction of the velocity of the particles, and the change of the velocity direction in turn causes the FB to change. The direction of change, FB is variable force.
