Electron acceleration using structured laser beams provides an attractive approach for developing compact acceleration systems applicable to high-energy density physics. This work presents a theoretical analysis of electron motion driven by a Laguerre-Gaussian (LG) laser pulse under the influence of a static magnetic confinement field. The inherent orbital angular momentum and helical phase structure of LG beams generate azimuthal field components that, when interacting with the cyclotron motion induced by a uniform magnetic field, significantly modify the acceleration process. A relativistic Lorentz-force model is employed to capture the coupled dynamics, and analytical expressions are derived to estimate energy gain and trajectory variations for different laser and field conditions. Numerical simulations demonstrate that magnetic confinement strengthens longitudinal trapping, minimizes transverse spreading, and enhances overall energy transfer from the laser to electrons. The findings suggest that the synergy between LG beams and static magnetic fields can address key constraints of Gaussian-laser-driven acceleration, offering a viable route toward efficient, tunable, and compact laser-based electron acceleration systems.
