    a charged particle will move when put within electric field, because the field will provode a push on that particle on specifik direction....

    It's called Coulomb's law... \[F = {{1 \over {4 \pi \epsilon_0}} {{Q_1 Q_2}\over{r^2}}}\] http://en.wikipedia.org/wiki/Coulomb%27s_law

    The magnetic field is always in the y direction, However, you can enter Ex,Ey,Ez to add electric field to the system. The force for charge particle in the electric and magnetic field is \vec{F}=q\vec{E}+ q\vec{v}\times\vec{B} If the initial velocity is proportional to the magnetic field and there is no electric field presented, then the force \vec{F} is always perpendicular to the velocity \vec{v} and magnetic fiel d\vec{B}, which means that it is a circular motion q v B= m \frac{v^2}{r}, so P=mv =qBr , or \omega=\tfrac{v}{r}=\tfrac{qB}{m} which is a independent on the velocity of the particle. it only depends on \tfrac{q}{m} and magnetic field B.
