Abstract: This paper discusses the cycloid trajectory of a charged particle moving in a crossed uniform electric and magnetic field and how it is formed by a wheel rolling.In order to make the motion of the charged particle to be clear,we also use physical analysis to bring forward the formula of cycloid radius of curvature.

Key words: effective mass, electric field, magnetic field, cycloid, radius of curvature
