3 Dynamics of Charged Particles
A very useful way of becoming familiar with electric and
magnetic fields is by studying their action on moving charges. With this
aim, we have designed several experiences to show separately the action
of E and B fields, and finally the joint action of both fields.
3.1 Charge in a uniform electric field
The action of an external electric field E on a charge
q is given by the force F=qE. Given the initial
position and velocity, the equation of motion is integrated numerically
and the trajectory is plotted.
