带电粒子在匀强磁场中的运动一直是高考的高频考点和考查重点,磁场边界的多样性,使得带电粒子在匀强磁场中的运动轨迹多样,妙趣横生.一、直线边界(单边有界)磁场问题直线边界(单边有界)磁场问题可分两类:一类是带电粒子从直线边界射入,另一类是粒子源处在磁场中.若带电粒子从直线边界射入,其运动轨迹与进入磁场时的速度方向直接相
The movement of charged particles in a uniform magnetic field has always been the high-frequency test centers and test focus of examination, the diversity of the magnetic field boundary, making the trajectory of charged particles in a uniform magnetic field varied, and fun. First, the linear boundary ) Magnetic field problems Linear boundary (unilateral bounded) Magnetic field problems can be divided into two categories: one is charged particles from the linear boundary into the other is the particle source in the magnetic field .If the charged particles from the linear boundary of the injection, the Motion trajectory and the direction of the speed of the magnetic field directly into phase
