带电粒子垂直于匀强磁场运动时,若仅受洛仑兹力作用,则粒子的运动轨迹为圆。洛仑兹力提供向心力:Bqv=mv2R=m(2πT)2R,对应的圆的半径R=mvBq,周期T=2πmBq。可以说这是一个比较浅显的知识。但涉及带电粒子在磁场中运动的问题却深浅不一,其中许多复杂问题的复杂性并不在于这
When the charged particles move perpendicular to the uniform magnetic field, if only the Lorentz force acts, the particle’s motion trajectory is a circle. The Lorentz force provides the centripetal force: Bqv=mv2R=m(2πT)2R, the radius of the corresponding circle R=mvBq, and the period T=2πmBq. It can be said that this is a relatively simple knowledge. However, the problems involving the movement of charged particles in a magnetic field are quite different. The complexity of many complex problems does not lie in this
