Abstract: In this paper,we analyze the law of motion of charged particles by the synergy of Lorentz force and resistance,including particles movement distance,rate changing over time,kinematic equation,trajectory,final displacement and maximum displacement.

Key words: uniform magnetic field, two-dimensional damping motion, logarithmic spiral, involute
