It seems like there is some necessary code missing, which I'm guessing looks like this:
import scipy.integrate as ig
import scipy.optimize as op
import scipy as sc
def rot(p,angle):
return [p[0]*cos(angle)-p[1]*sin(angle),p[1]*cos(angle)+p[1]*sin(angle)]
The code still doesn't produce the correct results. The integration routine complains a lot, and the spacing of the resulting field lines is wrong. — Preceding unsigned comment was added by 2605:E000:87C5:1200:29E4:985C:14C:5506 (talk) 21:46, 5 July 2019 (UTC)
