When you were choosing forces, why did you only need to choose "magnetic force"? IOW why did you not need to also choose particle-particle interaction to account for space charge (i.e. repulsion between like charges)? Or does the software do that automatically?

This is very useful and well done! How about an electron beam with a static electric field using the latest and greatest version of COMSOL?
would you mind sharing the file?
Thanks for the video! What if I can not choose a cut plane when setting the Poincare plot?
I mean, there are only two options: None, or From Parent. The cut plane 1 (xy plane, z=0) I created in the Dataset is not an option.
Hah, I got it. The method is: you choose "particle 1" as its dataset when building the cut plane.
Where can I find the tutorial to model the coil? Thanks in advance
is it electrospray?
can you make a positron coil too!!! wow
Awesome stuff! Thanks!
Where we find the existing magnetic file
how can I plot the magnetic field?
Is there anyway i can get this file that you have?
Hi Rob, you can download the model file from this page: www.comsol.com/model/magnetic-lens-10185
