The following simulation shows trajectory for a charged particle in electric and/or magnetic field.

\vec{F}=q\vec{E}+q\vec{v}\times\vec{B}

The magnetic field B is always in Z direction in the simulation, however, you can change Ex,Ey or Ez with a slider.
The initial condition is \vec{B}=B_0 \hat{z}, E=0 , \vec{v}=v_0 \hat{y} , so the result is a circular motion.

If you add E field, then you will find \vec{V_d}=\frac{\vec{E}\times\vec{B}}{|\vec{B}|^2} (E cross B drift).
The particle will drift along \vec{V_d}
