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.
