Charged particle motion in static Electric/Magnetic field
« on: February 13, 2010, 12:52:04 pm »
The following simulation shows trajectory for a charged particle in electric and/or magnetic field.

$vec{F}=qvec{E}+qvec{v}   imesvec{B}$

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 $vec{V_d}=frac{vec{E}   imesvec{B}}{|vec{B}|^2}$ (E cross B drift).
The particle will drift along $vec{V_d}$
