Hello, I'm also trying to work with the magnetic field definition. I made some attempts to get the field lines, but nothing came out. I'm got stuck and have no ideea how to get them.
These are my tryouts and something similar to what i would like to get. http://grasshopper3d.googlegroups.com/web/battery%20charge.jpg?gsc=5quuJQsAAAA1Eeahz0hcqW-5Fr8l_o1M definition (it's simplified cause i was trying to get it done on a simple example) http://grasshopper3d.googlegroups.com/web/magnetic%20curve%20_two%20points.ghx?gsc=t4JU_QsAAADqkNgPR-iGd6UVxJDKfC9C Any info on this is appreciated. Thanks a lot, Alex
