11.5 Confinement of positive ions and electrons with a static electric and magnetic field

Sitemap    Visualizing the electric field and some experiments

 

In the simulation program we can now visualize the electric field in the plane x= 0,5 mtr; see the images below.

The direction of the electric field is indicated by the arrows (this corresponds to the direction of the force a positive particle would experience).
The strength of the electric field is indicated by the color: the brighter red, the stronger the field.

Fig. 6a. Experiment with B = 2 T and the smallest possible size & fig.6b Potential (red = +,  blue = - )

Fig. 7. Experiment with B = 1.5 T  & fig.7b Potential (red = +,  blue = - )

Fig. 8a.. Experiment with B = 1.5 T  & & fig.8b. Potential (red = +,  blue = - )

The rings have a greater diameter. With the same voltage, they produce a stronger electric field  
and the particles will be more confined. This can be seen comparing figure 7, 8 and 9.
