In this paper, A test particle model is developed to study the electron acceleration in a magnetized-plasma filled waveguide by a twisted electromagnetic wave with variable amplitude and phase along the longitudinal position. With appropriately assigned initial values, the electron total energy gain is obtained by using numerical analysis without calculating dispersion relation. Numerical results show that as long as the twisted electromagnetic waves has a significant effect on the electron acceleration, during the passage of an electron through the waveguide, one may employ an optimum value of the external magnetic field to obtain the maximum energy gain.
