带电粒子在匀强磁场中做匀速圆周运动的轨道半径,由F_洛=F_向求得为:R=mv/Bq。然而在求解有关轨道半径与速度问题时,如何确定轨道半径是解决问题的难点和关键。本文将从以下几方面来介绍带电粒子在匀强磁场中轨道半径的确定方法。 1.已知带电粒子的入射角度,确定轨道半径
The orbital radius of a charged particle in a uniform magnetic field to make a uniform circular motion is obtained from F_lo=F_ to: R=mv/Bq. However, when solving the problem of orbit radius and velocity, how to determine the orbit radius is the difficulty and key to solve the problem. This article will introduce how to determine the orbital radius of a charged particle in a uniform magnetic field from the following aspects. 1. Knowing the incident angle of charged particles to determine the orbit radius
