• Problem set 04: Problem set 04 (mp4). I noticed after recording that a wrong sign appears on the components of the current vector field. On the web this is corrected and a vector graph is added for the current. I also add a vector graph that shows better the length of each one, by not requesting that the vectors are normalized. A solution is only found outside the cylindrical hole. As the origin of the coordinate system is thus avoided components of the solution that diverge at r = 0 are allowed and needed.
