Abstract [en] : The motion, velocities and trajectories of ions, and the effect of different electromagnetic field conditions on their motion are analyzed in detail. A numerical method is chosen to be used in a model to simulate ion trajectories in uniform and non-uniform electromagnetic fields. The outputs are stored in a file format which can be visualized using different software packages. Ion trajectories and their response to solar wind magnetic field and induced electric field are studied using the simulation model. Since this model can be applied to any solar wind condition, the Earth's moon environment is chosen as a real example for ion trajectories. After an analysis of the interaction of solar wind with the moon, a computational model for simulating its interaction with any other body is introduced. The outputs of this model are used to study ion trajectories at the moon wake. Finally, trajectories and velocities of ions coming from the moon's surface towards an observer orbiting the moon (in conditions of uniform electromagnetic field) are studied, and results for different observer positions are compared and discussed. This has applications for ion observations from a Lunar orbit.
