本文首先推导出带电粒子在匀强磁场中所受洛伦兹力的冲量在互相垂直(正交)方向上(x轴和y轴方向)的分量分别与其(y轴和x轴方向)的位置变化成正比,应用此特点可以方便地解决有关带电粒子在匀强磁场或电场磁场复合场中运动的相关问题,本文以三个高考压轴题为例进行应用解答。
In this paper, we first deduce the positions of the components of the Lorentz force impacted by the charged particles in a uniform magnetic field perpendicular to (orthogonal to) the x-axis and y-axis respectively (the y-axis and x-axis directions) The change is proportional to the application of this feature can be easily resolved on the charged particles in the uniform magnetic field or electric field magnetic field motion related issues in this paper to take the three college entrance examination pressure axis as an example to answer the application.
